[CityByTheValley]

Thanks for this. Very interesting data!

It's pretty funny that the Central San Jose council district was the most Republican in the city and indeed also more Republican than any municipality in the county...

I didn't even realize this until you mentioned it. It went from a 61 point margin to around 29 points, and indeed is now the most Republican part of the county despite being the center of San Jose. The Vietnamese love of Hillary/hate of 2016 Trump seriously was reversed and I'm sure the same types of trends happened in Orange County.

The Milpitas swing can’t be just from Vietnamese or Filipinos- neither group makes up more than 15-18% of the population there.

I think those groups are the largest two in Milpitas, no? You're right though, and come to think of it there are a lot of Chinese and Indians there as well. It does function as a moving spot for many techies who can't afford Cupertino/Sunnyvale and want a larger home given prices there are more like $500/sq ft versus $1,000/sq ft in most of the West Valley area. I think a similar dynamic will be at play in Fremont and we may see swings like this there. The swing still somewhat confuses me though because other places like this (Dublin, San Ramon, Pleasanton) seem to have swung to Biden.

Yeah let’s hope the Vietnamese and urban Latino swings were a one-time thing. I wonder which group was responsible for more of the swing? And I wonder what the ethnic breakdown of the Asian population in Districts 2, 3, 5, and 8 is...

I think the Vietnamese for sure swung more. District 7 is Latino majority, but I think the Vietnamese are higher propensity voters and clearly swung more than any other Asian group to Trump. It's funny that the best indicator for votes was still non-Hispanic White presence overall though.

In terms of ethnic breakdown, I'm not sure about Districts 2 and 3, but District 8 has a lot of Indians in the Evergreen area which has decent schools and nice homes. I'm somewhat surprised by the swing there since it is similar to 1, 6, 9, and 10 in terms of wealth, but the lack of non-Hispanic whites likely led to this happening. District 5 has a decent Filipino contingent, at least based off the city provided map.

Those other East Bay cities are much whiter, and have fewer to no Vietnamese or Filipinos. It bothers me that so much of the Asian swing could’ve just been from Vietnamese and maybe Filipinos- but tbh it bothers me that the Asian R swing even happened at all. I suspect it was more of a turnout issue (45 turning out more newly naturalized immigrants and low-propensity voters), but there may have been actual Vietnamese American vote switchers if the overall Viet swing was large enough.

[NOVA Green]

This took not too long but I got delayed since I wanted to break down San Jose by district to microanalyze all the swings given that it's basically an amalgamation of suburbs that range from Silicon Valley in the West to hills in the South and East.

Anyways, the swings in Santa Clara County were quite interesting. To paint a demographic picture, the county is 30% non-Hispanic White, 40% Asian, and 25% Latino with a population of around 2 million residents. It is also one of the wealthiest counties in the country with a median home values of $1 million and a median income of $125,000. I'll do a rundown based on city groupings and then breakdown San Jose in the end....

SNIP...

Santa Clara County
2016: 73.39 - 20.77 Clinton
2020: 72.64 - 25.23 Biden (R +5.20)

The county shifted over 5 points to the right, countering most of the smaller swings in the Bay Area. Milpitas and Districts 2, 3, 4, 5, 7, and 8 actually were responsible for the entire swing in the area, with the county swinging 0.01 points leftward without them, speaking to how big the urban Latino and Vietnamese swings ended up being. The swing here interestingly makes Santa Clara County the only one out of the 20 wealthiest counties nationwide to move rightward, and indicates a need for Democrats to keep in touch with their urban constituents as much as they try to focus on new ground.

I just wanted to say, as someone who lived in Santa Clara County for a Year (Cupertino) back in the early 2010s with a Tech Sector contract temporary job project assignment, this was a fascinating and well written "Executive Level Summary" of Santa Clara County.

Also, for a relatively new poster this is clearly an effort level and high quality post--- Belated welcome to the Forum!

One item which may have impacted some of the larger swings among working-class Latino and Asian-American voters within Silicon Valley, is the disproportionate impact of COVID-19 employment picture.

There was an article I read several Months back (Politico?) that described the dual structure of employment.

Large Tech Facilities basically shuttered their doors, moved all of their direct employees to working remotely, while simultaneously paying working-class contract employees more heavily involved in Facility Services (Custodial, Food Service, etc...) for a period of time.

Now that arrangement has effectively ended in most tech facilities in the South Bay and direct tech sector employees are basically "permanently" working remotely and "support workers" are out of work and filing for unemployment.

Considering that many of these workers are effectively highly skilled within their occupational categories, and are effectively SMEs in working their respective trades within highly demanding Tech Sector SOWs and MSAs, there really isn't anywhere for them to go without taking significant pay cuts, especially with increased competition for jobs, with similar occupational categories in public schools also shut down.

Thoughts?

I'm guessing SME = Small and Medium Sized Enterprises, SOW = Source of Wealth/Work, and MSA = Metropolitan Statistical Area?

Close but not close to any Cigar:

SME= Subject Matter Expert
SOW= Scope of Work
MSA= Master Service Agreement

These are typical MNC 500 terms which are typical contract law sort of scenes...

Many of these companies shipped all of our MFG and Testing Ops Overseas in some cases (25) Yrs back....

I still work in a  Tech sector MFG Facility, despite the off-shoring and sub-contracting of jobs....

Still debates / arguments in the smoking & break areas of the Factory regarding "how bad was Trump really"....

Hell... was talking with fellow smokers in Houston, Texas when Trump was first becoming a "thang"

Fourth consecutive county sweep for Democrats in Contra Costa County as no Republican presidential nominee has won a city here since 2004 when George W. Bush carried Brentwood, Clayton, and Danville.

Sacramento County would be interesting.  I gather Trump won Citrus Heights and unincorporated while Biden everything else so interesting to see that one.  Marin and Santa Cruz counties I am assuming are all Biden blowouts.

Sorry if it's already been mentioned, but how did Cupertino vote in 2020 compared to 2016?

Off the top of my head, almost one quarter of its population is south-Asian (Indian/Bangladeshi).

Here are the official results for Sacramento County. I didn't include the swings since write-in votes were not made available by city in 2016 (and there were a lot here; write-ins made up 1.72% of the final countywide vote in 2016), so take the 2016 results with a grain of salt.

I apologize if I made any errors with the colors anywhere. This is a big one.

There are no real surprises here when you look at overall trends everywhere else. Los Angeles County has a great deal of restaurant and retail jobs in the suburban areas that swung towards Trump, so Trump campaigning on re-opening everything probably helped him a great deal. Most of Biden's gains were in areas with higher white populations.

I remember it swinging pretty Republican in 2008 and 2012 but then it swung pretty hard to Hillary in 2016, now only to swing against Biden pretty substantially. What the heck is going on in 90210?!

*Note: Jo Jorgensen received an usually high 3.46% of the vote in Ridgecrest. I think I saw somewhere that this city was also Gary Johnson's best city in California in 2016 (he got 7.36% of the vote here). Anyone know anything about this place and its libertarian penchant?

Isolated places often have more people who prefer third parties.

It's most certainly the closures of businesses and the rent moratoriums. Lots of property owners live in Beverly Hills and hold deeds throughout the county.

I apologize if I made any errors with the colors anywhere. This is a big one.

There are no real surprises here when you look at overall trends everywhere else. Los Angeles County has a great deal of restaurant and retail jobs in the suburban areas that swung towards Trump, so Trump campaigning on re-opening everything probably helped him a great deal. Most of Biden's gains were in areas with higher white populations.

Oof, Los Angeles proper swung 7% R... I really don’t know how you can argue that COVID-19 didn’t help Trump electorally.
