Most Democrat and Republican city in each state with description

[thebeloitmoderate]

For me since I live in Wisconsin. Most D- Madison because of the college influence, tolerable population, etc. Most R- Some rural town up north- Uneducated WWC people, deer hunters, etc.

[Roll Roons]

NJ:
Most Democratic is probably East Orange, a 90% Black suburb just west of Newark
Most Republican is Lakewood, an Orthodox Jewish bastion.

[GregTheGreat657]

NY
Most D: Ithaca, a small city in the Finger Lakes region home to Cornell University and Ithaca College
Most R: Morehouse, an incredibly small, extremely white town in the Adirondacks, with a population density of about 1 person per 2 square miles

[thebeloitmoderate]

For California
Most democrat: Berkley- Home to the University of California
Most Republican; Norco an exurban community not far from Los Angeles and by the city of Corona.

Real cities have more than 50K people, so I'm only doing those, and the data is based on the 2020 US Presidential election and 2020 US Census. I'll do my own state right now, but if anyone wants me to have a go at theirs I'll try it out. Census-Designated Places are included.

Top Five Democratic - FLORIDA

• D+77.9 - Lauderhill, Broward County (Population 74,482) - majority-Black suburb in Northern Broward County that has undergone a stunning demographic transition over the last few decades (its Black population in 1970 was virtually 0). Fast-growing and receives large amounts of immigration from Miami Gardens and North Miami every year. Very large Jamaican and Haitian communities
• D+69.8 - Miami Gardens, Miami-Dade County (Population 111,640) - Another majority-Black suburb in Northern Dade County where the Black population is receding as Hispanics arrive. Facing moderate growth, mostly from Hispanics, but hit peak population of 125K back in 2000
• D+69.0 - Pine Hills, Orange County (Population 66,111) - Fast-growing majority-Black city in Western Orange County, adjacent to Orlando. Large Haitian community.
• D+58.2 - North Miami, Miami-Dade County (Population 60,191) - Slowly-growing majority-Black city South of Miami Gardens and North of Miami, has an arm that reaches into the coast, so it has large Hispanic and White areas as well
• D+50.8 - Gainesville, Alachua County (Population 141,085) - College town, dominated by the presence of the University of Florida

Top Five Republican - FLORIDA

• R+35.6 - Westchester, Miami-Dade County (Population 56,384) - Suburb that is nearly 70% Cuban in West Dade, added a significant chunk of land over the 2010s which on paper caused a population boom of 90%. However, directly comparing the area itself, it has lost population over the 2010s (and through the 2000s as well). Can be considered an extension of West Miami
• R+34.3 - Hialeah, Miami-Dade County (Population 223,109) - Over 70% Cuban, Northwest Dade, a very large suburb that began to shrink in the 2010s as Cuban inflow dried up.
• R+33.6 - The Villages, Sumter County (Population 79,077) - Rapidly-growing retiree haven to the Northwest of Orlando. Median age is far above 65. Holds the majority of Sumter County's population
• R+32.8 - Tamiami, Miami-Dade County (Population 54,212) - Over 60% Cuban, another shrinking suburb in the far western reaches of Dade County. Has a significant Nicaraguan presence
• R+25.4 - Cape Coral, Lee County (Population 194,016) - A massive, rapidly-growing suburban city making up Lee County's northern peninsula. Lots of canals.

Where did you got the info Bro?

-SNIP-

Where did you got the info Bro?

Dave's Redistricting App (an in-browser tool, you don't have to install anything), you can navigate to a map of your state, on the top left of the page it allows you to switch between "County", "City", "Precinct", and "Block". Click "City", hover over the city you want the data of, and on the bottom-right, you can see results for whichever election you'd like.

You'll have to make an account there if you want to see the results of a specific election, as by default it's set to a composite. For example, in your state of Wisconsin, detailed results are available for:

2020 President
2018 Senator
2018 Governor
2018 Attorney General
2016 President
2016 Senator

In Wisconsin the top Democrat and Republican cities in no order
Madison- at 84.1 Percent of the residents that voted for Biden population 269,840-State capitol, and thanks not just home to UW madison, but to other colleges such as Edgewood, Madison Tech, It remains a very liberal city, and the sky high turnout in 2020 (although in other elections there is moderate to high but not record breaking) contributed to Biden's win in Wisconsin. However it is mostly white and fairly diverse unlike Milwaukee. But the whites are mostly college educated liberals. And the record growth not as astronomically high as Austin or Phoenix on par with Columbus could make the Madison Area swing left in future elections.
Milwaukee- 78 percent of the city voted for Biden population of 577,222. Although the DNC was held there virtually, some african american neighborhoods saw lower turnout than in 2016, and in fact most if not all the minority neighborhoods swung to Trump while the white neighborhoods swung to Biden. The city is also less college educated and even UW Milwaukee is in a neighboring suburb.
Menominee- At 81 percent it is a native American reservation county technically and given that Native Americans always vote Democrat this is no surprise. But they also suffer from abysmal low voter turnout, and this is why WI-8 is red.
Most Republican
Waukesha- 51 percent of the population in Waukesha the biggest city in the WOW area voted for Trump but unlike other big suburban cities shockingly, Waukesha did not turned out as heavy as other suburban Wisconsin cities. And also another reason why Waukesha voted r in 2020 is because the population is mostly white unlike other suburban cities.
 Rochester- nearly 70 percent voted for Trump and given it's location in Racine county and not in the WOW region it is less college educated and predominantly white this was no surprise.

This is incorrect. Shorewood Hills is more Democratic than Madison and Shorewood is more Democratic than Milwaukee.

[I spent the winter writing songs about getting better]

Anyway in Minnesota the answer is actually not either of the Twin Cities but a town on the Red Lake Reservation called Ponemah. The most Republican is Prinsburg, a heavily Dutch enclave in southwest Minnesota.

This is incorrect. Shorewood Hills is more Democratic than Madison and Shorewood is more Democratic than Milwaukee.

BRTD is correct. Biden won Shorewood Hills by a spread of 83.51 points whereas Madison was D+ 69.80, making it the second-most Democratic city in Wisconsin (at least in 2020).

The most Republican "city" in Wisconsin is Oostburg, a village of about 3,000 people in Sheboygan County. It sounds similar to Prinsburg (Minnesota's most Republican municipality) in that it has a rich Dutch heritage. It's located about 15 miles south of the city of Sheboygan. Trump won Oostburg by 61.94 points in 2020. Another tiny (population ~250) village named Potter (Calumet County) was close behind with a victory of 61.40 points for the former guy.

Top Five Democratic - North Carolina

• D+71.3 - Chapel Hill, Orange County (Population 61,960) - Majority white college town. 62% White, 17% Asian, just 11% Black. Very liberal and highly-educated.
• D+68.2 - Durham, Durham County (Population 283,506) - Next door neighbor to Chapel Hill. Much more racially diverse -- 38.6% White, 38.6% Black, 15.3% Hispanic, 6.9% Asian. Similar reasons for voting D and big high-tech sector as well
• D+56.7 - Asheville, Buncombe County (Population 94,589) - White tourism town in the Western Mountains. 74% White and 12% Black. Again, very liberal and highly educated.
• D+43.3 - Greensboro, Guilford County (Population 299,035) - Racially diverse big city in western half of the state. Used to be a lot more Republican (Was just Hagan +33.6 in 2014) but has swung left since then. 38.6% White and 44.8% Black.
• D+43.2 - Charlotte, (Population 874,579) - State's biggest city. Similar political make-up to Greensboro. Was just Hagan +30.7 in 2014, now a lot bluer. 39.7% White, 35.4% Black. Interestingly enough, still a lot closer for non-Presidential races -- was just Cunningham +37.1, though the 2016 Lieutenant Governor Race (Just Coleman +29.1) is probably the best Republicans are doing here for a long time.

Top Five Republican - North Carolina

• R+25.1 - Mooresville, Iredell County (Population 50,193) - Exurb of Charlotte. Swung left since 2016 -- was Trump +33 then. Was one of the places that sunk McCrory in 2016 (anger over local toll disputes led him to get just a 3600 vote margin here, even as Trump got a 6200 margin). 70% White. 13% Black. 6% Asian.
• R+10.4 - Kannapolis, Rowan and Cabarrus Counties (Population 53,114) - Also a exurb of Charlotte. Diversifying pretty rapidly (Went from 66% White in 2010 to 55% now.) Hasn't swung left as much as that might indicate though -- Trump +16.6 in 2016 and +10.4 in 2020. 55% White, 25% Black, 16% Hispanic.
• R+3.8 - Gastonia, Gaston County (Population 80,411) - Another Charlotte exurb (you may be beginning to notice a trend here) although it's also it's own city in a way the others aren't (Charlotte's suburban growth has extended less westwards than east or northwards.) 51% White, 33% Black, 13% Hispanic. Has gotten more diverse since 2010, when it was 62% White, 28% Black, and 9% Hispanic. Hasn't swung too much either way -- went from Trump +6.5 in 2016 to Trump +3.8 in 2020, similar to the nation.
• R+3.6 - Jacksonville, Onslow County (Population 72,723) - Our only non-Charlotte exurb on this list. A military base/beach town in Eastern NC. Was 62% White, 13% Hispanic, and 22% Black in 2010, 53% White, 19% Hispanic, and 22% Black in 2010. Not actually growing too much -- total population rose by just 2,000 from 2010 to 2020, even as the county as a whole grew by 11.3% and more than 22,000 people, probably because most of the growth is going to the nearby suburbs. Went from Trump +9.9 in 2016 to +3.4 in 2020.  
• D+1.6 - Concord, Cabarrus County (Population 105,240) - Another Charlotte exurb. Growing rapidly -- went from 80k in 2010 to 105k now. 66% White, 18% Black, and 13% Hispanic in 2010 to 53% White, 25% Black, and 14% Hispanic. Swinging hard left -- Trump +9.8 in 2016 to Biden +1.6 in 2020.

I played with DRA to get this, but there are so many 50k suburbs in this state that I admit I could have missed one.
* = city extends out of the county a small amount. Missouri City has 1 neighborhood in Harris County for instance.

Top Five Democratic - Texas

• D + 72.51 - DeSoto, Dallas County (Population 56,145) - Suburb in the county's southwest that has gradually become majority-black and remained middle-class. 10% White, 17% Hispanic, 72% Black, 2% Native American. Household income slightly above national average, 4-year degrees slightly below.
• D + 54.99 - Austin, Travis County* (Population 961,855) - State capital & tech hub, with the University of Texas and a "weird" reputation that may be fading with its massive growth. 47% White, 33% Hispanic, 9% Black, 11% Asian. Highly educated and high-income.

• D + 40.72 - Missouri City, Fort Bend County* (Population 74,259) - In a diverse, middle-class area of Houston's suburbs, the black plurality pushes it more Dem than its more Asian & white neighbor Sugar Land. 19% White, 19% Hispanic, 43% Black, 19% Asian. High income and education.
• D + 38.25 - San Marcos, Hays County* (Population 67,553) - a growing small city south of Austin, centered on Texas State University. 42% White, 41% Hispanic, 9% Black, 8% Asian. Average education but low income.

Tennessee with the 50K limit (a lot of city limits stop short of that in Tennessee, so it's a limited list that covers everything except the range between R+0.4 (Clarksville) and R+17.8 (Franklin).

Top Five Democratic - Tennessee

• D + 55.3 - Memphis, Shelby County (Population 633,104) - Major city, but the one that's by far the least trendy and slowest growing of the Big Four cities in Tennessee.  63% Black, 24, White, 9% Hispanic.
• D + 33.4 - Nashville, Davidson County (Population 689,447) - Nashville and Davidson County are consolidated, but a few legacy independent cities remain.  This calculation excludes the legacy independent cities (with them, it's D+32).  Very trendy, fast-growing city.  53% White, 26% Black, 14% Hispanic.
• D + 18.8 - Chattanooga, Hamilton County (Population 181,099) - An ancestrally Republican city in East Tennessee that has gained a little bit of a yuppie reputation in recent years.  Located near the mountains with a lot of outdoor opportunities.  55% White, 31% Black, 9% Hispanic.
• D + 16.0 - Knoxville, Knox County (Population 190,740) The chief population center of East Tennessee and home to the University of Tennessee.  Ancestrally extremely Republican and still fairly Republican for a regional population center with a state flagship university.   68% White, 19% Black, 8% Hispanic
• D + 1.2 - Jackson, Madison County (Population 68,205) - A stagnating, very racially polarized city in West Tennessee.  46% Black, 46% White (43B/49W by VAP)...and it votes exactly like you'd expect it to.

Top Five Republican - Tennessee

• R + 42.8 - Kingsport, Sullivan County (Population 55,442) - Northeast Tennessee.  I haven't spent a ton of time there, but it's a very sprawling area ("what's this a suburb of, again").  87% White.
• R + 30.0 - Spring Hill, Williamson and Maury Counties (Population 50,005) - Insanely fast growing exurb of Nashville along the "favored quarter".  It didn't exceed 1000 people until the 1990 census and went from 7715 in 2000 to over 50K in 2020.  79% White, 8% Hispanic, 7% Black.  Slowly diversifying and trending Democratic as it grows from a rural area to a true suburb.  Was Trump +41 in 2016 and had the sharpest swing against Trump in all of Williamson County.
• R + 28.9 - Collierville, Shelby County (Population 51,324) - Wealthy suburb of Memphis that was virtually entirely Republican a decade ago.  Was Trump +39 in 2016.  By Tennessee standards, it has an extremely large Asian community.  67% White, 14% Asian, 13% Black.
• R + 28.7 - Hendersonville, Sumner County (Population 61,753) - Large middle-class suburb of Nashville (except for the lakefront areas being more wealthy).  Hasn't trended as far to the left as the suburbs to the south of Nashville.  77% White, 10% Black, 6% Hispanic.
• R + 22.0 - Bartlett, Shelby County (Population 57,786) -  Another fairly well-off suburb of Memphis.  Very similar to Collierville (and Germantown, which only missed this list due to being barely too small).  68% White, 22% Black.

Top Four Democratic - Louisiana

• R + 10.67 - Lafayette, Lafayette Parish (Population 121,374) - known as the heart of Cajun Country and home of the state's 2nd-largest university. 57% White, 6% Hispanic, 32% Black, 3% Asian. High education, near national average income.
• R + 6.18 - Kenner, Jefferson Parish (Population 66,448) - a bit further out than Metairie, and a bit less affluent, known for housing New Orleans' airport. 40% White, 30% Hispanic, 24% Black, 6% Asian. Above state averages of income and education.

Bonuses

• R + 34.87 - Houma, Terrebonne Parish (Population 33,406) - Down on the bayou near the swampy coast of Cajun Country, it surpasses the larger Lafayette as the state's reddest metropolitan city. 58% White, 7% Hispanic, 26% Black, 7% Native American. Education and income below state average.
• R + 69.69 - Central, East Baton Rouge Parish (Population 29,565) and R + 49.24 - Prairieville, Ascension Parish (Population 33,197) - Closing it out like the Dem bonuses with 2 similar examples, these are both wealthy suburbs of Baton Rouge, with their margins due to racially polarized voting and significant white majorities.

Belleville is D+18.7. A lot of other Metro East suburbs are red though.

Top Five Democratic - Illinois

• D + 83.3 - Evanston, Cook County (Population 78,110) - On the lakeshore just north of Chicago, the college town of Northwestern University. 59% White, 10% Hispanic, 18% Black, 12% Asian. High income and education.
• D + 80.3 - Oak Park, Cook County (Population 54,583) - One of the most liberal inner suburbs in the U.S., it's just west of the mostly-black Chicago neighborhood of Austin. It was the home of Frank Lloyd Wright, who designed many of the local landmarks. 62% White, 8% Hispanic, 22% Black, 7% Asian. Even higher income and educational attainment than Evanston.
• D + 66.7 - Chicago, Cook County (Population 2,746,388) - A vast city of many neighborhoods, where only a few outlying precincts supported Trump over Biden. 35% White, 27% Hispanic, 30% Black, 8% Asian. Near national average income, with more college degrees.
• D + 64.4 - Cicero, Cook County (Population 85,268) - To the south of the Austin neighborhood, a city with a supermajority of Mexican descent. In the past, it was more a Czech area. 6% White, 89% Hispanic, 5% Black, 7% Native American. Below national averages in income and education.
• D + 52.0 - Waukegan, Lake County (Population 89,321) - Closer to Kenosha than Chicago, a more working-class lakeside city that was the home of Ray Bradbury and Jack Benny. 16% White, 60% Hispanic, 19% Black, 6% Asian. Below national averages in income and education.
• Among the bluest cities below the 50k line are North Chicago, a Hispanic-plurality city south of Waukegan with a naval station, and the various majority-black suburbs south of the South Side.
  

Top Five Republican - Illinois

• R + 4.8 - Orland Park, Cook County (Population 58,703) - A cluster of southwestern Chicago suburbs voted Trump, but all others are smaller. 81% White, 8% Hispanic, 4% Black, 6% Asian. Above average income and education.
• R + 0.4 - Decatur, Macon County (Population 70,522) - Near Illinois's center, it's still driven by industrial jobs with companies like ADM and Caterpillar. 63% White, 3% Hispanic, 30% Black, 2% Native. Below average income and education.
• D + 2.7 - Tinley Park, Cook County (Population 55,971) - Now for the least Democratic cities, this suburb is adjacent to Orland Park and demographically similar. 78% White, 8% Hispanic, 7% Black, 5% Asian. Above average income and education.
• R + 12.3 - Springfield, Sangamon County (Population 114,394) - State capital known for its Abe Lincoln connections, it is one of the less-Democratic cities by virtue of its downstate location and annexing most of its suburbs, despite the government jobs. 68% White, 3% Hispanic, 23% Black, 4% Asian. Slightly more educated, with lower household income, than the national average.
• R + 13.9 - Oak Lawn, Cook County (Population 58,362) - also a southwest suburb, but closer to Chicago than the previous 2 mentioned. 64% White, 23% Hispanic, 9% Black, 4% Asian. Slightly above average income and education.

Bonuses

• R + 31.7 - Quincy, Adams County (Population 39,463) - It anchors a micropolitan area with Hannibal, Missouri. About as far west as you can go in the state, its electoral trend is pointing right. 86% White, 2% Hispanic, 9% Black, 2% Native. Below national averages in income and education.
• R + 16.4 - Pekin, Tazewell County (Population 31,731) - A county seat and suburb of Peoria, it is a former sundown town that maintains a white supermajority, like R+14.2 Granite City (a St. Louis suburb), and unlike Oak Park and Cicero mentioned in the D column. 90% White, 2% Hispanic, 3% Black, 2% Native. Below national averages in income and education.

Top Five Democratic - North Carolina

• D+71.3 - Chapel Hill, Orange County (Population 61,960) - Majority white college town. 62% White, 17% Asian, just 11% Black. Very liberal and highly-educated.
• D+68.2 - Durham, Durham County (Population 283,506) - Next door neighbor to Chapel Hill. Much more racially diverse -- 38.6% White, 38.6% Black, 15.3% Hispanic, 6.9% Asian. Similar reasons for voting D and big high-tech sector as well
• D+56.7 - Asheville, Buncombe County (Population 94,589) - White tourism town in the Western Mountains. 74% White and 12% Black. Again, very liberal and highly educated.
• D+43.3 - Greensboro, Guilford County (Population 299,035) - Racially diverse big city in western half of the state. Used to be a lot more Republican (Was just Hagan +33.6 in 2014) but has swung left since then. 38.6% White and 44.8% Black.
• D+43.2 - Charlotte, (Population 874,579) - State's biggest city. Similar political make-up to Greensboro. Was just Hagan +30.7 in 2014, now a lot bluer. 39.7% White, 35.4% Black. Interestingly enough, still a lot closer for non-Presidential races -- was just Cunningham +37.1, though the 2016 Lieutenant Governor Race (Just Coleman +29.1) is probably the best Republicans are doing here for a long time.

Top Five Republican - North Carolina

• R+25.1 - Mooresville, Iredell County (Population 50,193) - Exurb of Charlotte. Swung left since 2016 -- was Trump +33 then. Was one of the places that sunk McCrory in 2016 (anger over local toll disputes led him to get just a 3600 vote margin here, even as Trump got a 6200 margin). 70% White. 13% Black. 6% Asian.
• R+10.4 - Kannapolis, Rowan and Cabarrus Counties (Population 53,114) - Also a exurb of Charlotte. Diversifying pretty rapidly (Went from 66% White in 2010 to 55% now.) Hasn't swung left as much as that might indicate though -- Trump +16.6 in 2016 and +10.4 in 2020. 55% White, 25% Black, 16% Hispanic.
• R+3.8 - Gastonia, Gaston County (Population 80,411) - Another Charlotte exurb (you may be beginning to notice a trend here) although it's also it's own city in a way the others aren't (Charlotte's suburban growth has extended less westwards than east or northwards.) 51% White, 33% Black, 13% Hispanic. Has gotten more diverse since 2010, when it was 62% White, 28% Black, and 9% Hispanic. Hasn't swung too much either way -- went from Trump +6.5 in 2016 to Trump +3.8 in 2020, similar to the nation.
• R+3.6 - Jacksonville, Onslow County (Population 72,723) - Our only non-Charlotte exurb on this list. A military base/beach town in Eastern NC. Was 62% White, 13% Hispanic, and 22% Black in 2010, 53% White, 19% Hispanic, and 22% Black in 2010. Not actually growing too much -- total population rose by just 2,000 from 2010 to 2020, even as the county as a whole grew by 11.3% and more than 22,000 people, probably because most of the growth is going to the nearby suburbs. Went from Trump +9.9 in 2016 to +3.4 in 2020.  
• D+1.6 - Concord, Cabarrus County (Population 105,240) - Another Charlotte exurb. Growing rapidly -- went from 80k in 2010 to 105k now. 66% White, 18% Black, and 13% Hispanic in 2010 to 53% White, 25% Black, and 14% Hispanic. Swinging hard left -- Trump +9.8 in 2016 to Biden +1.6 in 2020.

Just FOUR cities in NC broke for Trump? Genuinely shocked.

[I spent the winter writing songs about getting better]

50k in some places can be just too high of a cutoff. For example Minnesota only has 19 cities over 50k (St. Louis Park falls just short), and of those only one voted for Trump (Lakeville) and even that was quite close. I might do it for Minnesota but with a cutoff like 10k instead.

Just FOUR cities in NC broke for Trump? Genuinely shocked.

NC Republicans are concentrated in "countrypolitan" areas that don't have enough people to qualify for the list, but vote 65-35 Republican. There's several counties like this, especially around Charlotte that have populations in the 6 digits

50k in some places can be just too high of a cutoff. For example Minnesota only has 19 cities over 50k (St. Louis Park falls just short), and of those only one voted for Trump (Lakeville) and even that was quite close. I might do it for Minnesota but with a cutoff like 10k instead.

St. Louis Park qualifies on the Census and falls below for the 2021 estimate. 20k would get you around 60 cities, and 10k would get you up to 100. Here's trying out a low 5k limit for a low-population state. Not many surprises in this one:

Top Five Democratic - Montana

• D + 42.0 - Missoula, Missoula County (Population 73,604) - It has a well-deserved liberal reputation and is centered on the University of Montana. Like all the other Dem-leaning examples, it's in the mountainous western half of the state. 83% White, 5% Native, 6% Hispanic, 3% Asian. High education, below state average income (using state since all examples are below national average).
• D + 33.8 - Bozeman, Gallatin County (Population 53,318) - The home of Montana State, it's growing more dramatically and has now become one of Montana's major cities. 86% White, 3% Native, 5% Hispanic, 3% Asian. Higher education and income than Missoula.
• D + 25.1 - Helena, Lewis and Clark County (Population 32,182) - The state capital and an old gold rush town in the mountains. 87% White, 5% Native, 4% Hispanic, 2% Asian. High education, income even with Bozeman.
• D + 25.0 - Whitefish, Flathead County (Population 7,754) - One of the ski resort towns that dot the West, with many outdoors and cultural attractions. 91% White, 3% Native, 3% Hispanic, 2% Asian. High education, median income low but per capita is high.
• D + 14.1 - Butte, Silver Bow County (Population 34,592) - Coming in just ahead of Livingston in Park County, the city of Butte has a small university, Montana Tech. It has made the list despite annexing the vast majority of the county. 88% White, 4% Native, 5% Hispanic, 1% Asian. Lower income and education than state average.

Top Five Republican - Montana

• R + 65.4 - Sidney, Richland County (Population 6,351) - Far from Missoula in several ways, it's more working-class, agricultural, and near the North Dakota border. 83% White, 6% Native, 7% Hispanic, 2% Asian. Low education, above average income.
• R + 40.3 - Miles City, Custer County (Population 8,371) - Similar to and upstream of the previous, this is the largest city between Billings and Dickinson, ND, in one of the sparsest regions of the country. 90% White, 4% Native, 3% Hispanic, 1% Asian. Slightly below average education and income.
• R + 39.2 - Lewistown, Fergus County (Population 5,963) - A more oil & gas-based economy in central Montana. 90% White, 4% Native, 3% Hispanic, 1% Asian. Low education and income.
• R + 39.1 - Laurel, Yellowstone County (Population 7,207) - A city with an oil refinery and rail yard that's close enough to Billings to commute. 81% White, 9% Native, 7% Hispanic, 1% Black. Low education, slightly below average income.
• R + 26.4 - Kalispell, Flathead County (Population 24,580) - Near Whitefish, but further down in the river valley, it's politically quite the opposite and more working-class. 87% White, 4% Native, 4% Hispanic, 2% Asian. Slightly below average education and lower income.

[Schiff for Senate]

Fifty thousand is actually way too low for CA. By my count, 75 cities have populations 100,000 or higher, so there are probably like 100+ cities with north of 50,000 people. So I'm actually making the benchmark 120,000 people. I believe 52 cities meet that bar (2020 Census). Aside from the city's county and population, I also mention its rank out of California's cities. Lastly, I included the sixth most liberal and conservative cities rather than just the five most. Incredibly, three of the bluest cities are right here in my home county of Alameda (in fact, all three are in west-northwest Alameda County). Four bluest cities are in the Bay Area.

Top Six Democratic - CALIFORNIA

• D+89.8 - Berkeley, Alameda County (Pop. 124,321; Rank 51st) - Straightforward. University city (near Oakland); home to UC Berkeley. Trump actually finished THIRD here in 2016, behind Jill Stein - this time, he received about twice as many votes as third-party and independent candidates combined (4.0% to 2.0%). 2010 to 2020 growth was 10.4%. It's 50% non-Hispanic white, 20% Asian and 14% Hispanic. Density is nearly 12,000 people per square mile. Naturally much more educated and wealthy than the US as a whole (percent of 25+ who have a bachelor's degree or higher in the US is 32.9%; it's 73.1% in Berkeley; and MHI is over $90,000 compared to less than $70,000 nationally).
• D+84.1 - Oakland, Alameda County (Pop. 440,656; Rank 8th) - Situated in the northwest portion of Alameda County, near Berkeley. Definitely one of the most diverse cities in the country. It's plurality white, but it's just 27% non-Hispanic white, 27% Hispanic, 24% black, and 16% Asian. MHI is higher than the US, at over $80,000 (US's is under $70,000), and it's more educated, with the bachelor's degree or higher rate for 25+ at 46.1% to 32.9% nationally. Density is close to 8,000 people a square mile.
• D+72.6 - San Francisco (Pop. 873,965; Rank 4th)Butt of right-wing jokes and major symbol of cultural, social and economic progressivism (but with an emphasis on the first two). A lot of conservatives see San F.'s population summarised with three H's (homos, hobos and hippies), and they aren't wrong. Gay capitol of the USA, home of the notorious Nancy Pelosi, and has a massive hippie counterculture (arguably more than any other city). Haight and Ashbury and everything. Anyway, 39% non-Hispanic white, 34% Asian (including 21% Chinese), 16% Hispanic (8% Mexican), and 5% black. 35% atheist and a majority are non-Christian. Density is nearly 19,000 people a square mile. Very educated (58.8% of 25+ with bachelor's or higher to 32.9% nationally) and wealthy (MHI is close to $120,000 - more than 75% higher than the national MHI).
• D+56.3 - Hayward, Alameda County (Pop. 162,954; Rank 34th) - Also in western Alameda. MHI is $91,490, much higher than the national, but the education level is surprisingly a bit lower than national - 29.8% of 25+ with bachelor's+, compared to 32.9% nationally. A large plurality of the population is Hispanic - 39.5% Hispanic, 30% white and 28% Asian.
• D+56.2 - Pasadena, Los Angeles County (Pop. 138,699; Rank 44th) - Bluest SoCal city. It's a suburb of LA, and quite dense (north of 6,000 people a square mile). Very narrowly plurality Hispanic: 34.9% Hispanic and 34.6% non-Hispanic white, with 18% Asian and 8% black. MHI is high, at over $85,000, and education wise, a majority of those 25 and over are armed with bachelor's degrees (if not higher).
• D+55.8 - Sunnyvale, Santa Clara County (Pop. 155,805; Rank 36th) - In the Bay Area. Density: 6,800 per square mile. 29% non-Hispanic white, 17% Hispanic, and a solid 48% Asian, making it strongly plurality-Asian. MHI is over twice the national - over $150,000 - and 65.9% of 25+ people have at least a bachelor's degree. Grew at a rate faster than national from 2010 to 2020, but not that much faster.

Top Six Republican - CALIFORNIA

• R+14.1 - Clovis, Fresno County (Pop. 120,124; Rank 52nd) - North suburb of Fresno that's been rapidly growing (grew over 25% from 2010 to 2020). The density is nearly 5,000 people a square mile. Just barely majority-minority - 49.5% non-Hispanic white, 33% Hispanic and 11% Asian. Bachelor's+ rate for 25+ is a little higher than the national; MHI is over $80,000.
• R+10.1 - Visalia, Tulare County (Pop. 141,384; Rank 42nd) - A good amount north of Bakersfield, though Tulare borders Kern and their border separates NorCal from SoCal. It has close to 4,000 people a square mile. Majority-Hispanic: just 38% of the population is non-Hispanic white, while 51% is Hispanic (also 6% Asian and 3% black). The bachelor's+ rate for the 25+ is very low, at 22.5%. MHI is very similar to the national, but just a smidge lower.
• R+3.3 - Huntington Beach, Orange County (Pop. 198,711; Rank 23rd) - Leftwards trending, affluent suburb of LA on the coast. Classic Orange County, historically Republican suburbia, that's been diversifying (though it grew only 4.6% from 2010 to 2020) and liberalising to the point that Trump's 2020 margin was quite narrow (it was Romney+16 in 2012, Trump+6 in 2016 and Trump+3 in 2020 - this city even went for Goldwater in 1964 and presumably last went blue in 1936, or maybe even before that). It is 61% non-Hispanic white, 19% Hispanic and 13% Asian. Unsurprisingly, the MHI is very high, at close to a hundred thousand, and 43.6% of the 25+ population has bachelor degree or higher.
• R+3.1 - Bakersfield, Kern County (Pop. 403,455; Rank 9th) - The biggest city in CA to go for Trump, by a lot. In the northern part of SoCal. Home to a good number of undocumented immigrants. It and Kern have been moving leftwards (Bakersfield went red by 12.7 points even in the 2008 wave), but both are historically fairly conservative, and though the margin was narrow, Trump held on to Bakersfield (he won Kern more comfortably, by about 15 points or so if I remember right). Not even 3,000 people a square mile. It is the "frontier delineating" the Sureno (Southern) and Norteno (Northern) gangs' territories. Republicans Devin Nunes and Kevin McCarthy are from the area. It is 29% non-Hispanic white, and majority Hispanic. High poverty rate and the MHI is a bit lower than the national rate. Bachelor's degree + rate for the 25+ is a lot lower than the national rate - at just 22.5%.
• R+1.4 - Roseville, Placer County (Pop. 141,500; Rank 39th) - In northeast CA. MHI is over $95,000, and bachelor's degree + for those 25+ is also reasonably high, at 43.5%. 66.4% non-Hispanic white, 16% Hispanic, 12% Asian.
• D+0.9 - Simi Valley, Ventura County (Pop. 126,356; Rank 48th) - Near the Ventura County - LA County border. Was Trump+4 in 2016, Romney+12 in 2012, and Bush+23 in 2008, so it's been trending leftwards recently, but not that fast. MHI is close to a hundred thousand, and it's not particularly educated, with 33.9% of 25+ having a bachelor's degree or more. Density is apparently exactly 3,000 people a square mile, which is neat.

[Mr. Smith]

Kinda surprised San Rafael isn't in the top 5 D, given how Marin often defeats San Francisco for most Democratic in the state now...kinda bizarre to think about given how it used to be one of the biggest Republican strongholds....a bit like the Vermont to SF/Alameda's MA/RI  I s'pose.

[If my soul was made of stone]

It's very alienating and masculine-nerd-compartmentalizing Atlas Brain how folks here are only viewing these places as a collection of statistics relevant to #trends rather than engaging with their geography or history or economy or sociopolitical culture. Gee, I wonder why Butte is Dem-leaning despite being Muh Unwashed Uneducated WWC (no, it has nothing to do with Montana Tech, you dingus)...
