Pairs of states that are politically similar?

[Tekken_Guy]

What pairs of states are have similarities to each other in their electoral history?

[Roll Roons]

-North and South Dakota
-Nebraska and Kansas
-Alabama and Mississippi

[Bismarck]

Indiana and Missouri are very similar now although perhaps not historically.

[Del Tachi]

Some of the MS River states.  Tennessee, Missouri and Kentucky have voted the same in every election going back to 1960, I believe

[Gass3268]

Illinois and New Jersey have voted the same in every single Presidential election since 1888, with the exception of 1948.

[TDAS04]

Arkansas and West Virginia are pretty similar for non-neighboring states.

[TheElectoralBoobyPrize]

Hot take: Louisiana and Arkansas. They haven't voted differently since 1964. They also voted for the winner in every election from 1972 to 2004, but they become both became safe red states in 2008 (I would argue they were lean red in 2000 and likely red in 2004).

They aren't demographically similar, but north Louisiana is somewhat like Arkansas.

Oregon and Washington. Part of the same bioregion and dominated by a big metro area. When they've voted different it's always been red Oregon and blue Washington, likely due to the Portland metro being smaller than the Seattle metro.

Except for 1912.

Last time north and South Dakota voted differently was 1916 with nd going for Wilson and sd for hughes

[TheReckoning]

Surprised no one mentioned Colorado/Virginia.

You got me, but to be fair that election was unusual all around and was essentially a three way race.

[Radicalneo]

Pennsylvania and Michigan

[Amenhotep Bakari-Sellers]

IN and IA now Ds are going after NC and SC even if we don't win SC James Harrison is looking at 28 Tim Scott is retiring

Virginia, Colorado, and Minnesota formed a triad for a while, but they seem to be diverging.

[Samof94]

-North and South Dakota
-Nebraska and Kansas
-Alabama and Mississippi

Kansas elects Ds as Gov often.

[Born to Slay. Forced to Work.]

Alabama and Mississippi have voted for the same presidential candidate since 1844 IIRC.

This doesn't make too much sense to me. CO and VA voted R from 1952 to 2004 with once being D (1964) while MN voted R in 1952-1956-1972. CO and VA are very much the same but adding MN is really weird imo.

They match during the 2008-2020 period. States "politically controlled" mostly by a single huge and pretty blue metro, with the state Democratic Party taking on the characteristics that would be expected from having that base, and consistently winning statewide races by high single digit margins, while legislative chambers flip frequently.

New York and Illinois. Both have statewide elections that are a foregone conclusion due to the presence of a single mega city, and both were swing states presidentially up until 1992, had some vestiges of Republican success at the Senate and gubernatorial level for another decade, and then fizzled out.

Ahh I see, so basically down ballot. I see and agree!

I think the reason it's diverging now because outside of MSP, Ds have very few state legislative seats  whereas in VA and CO, their legislative coalition is far more geographically diverse and their geographic distribution is better.
