Guess the previous county's location and demographics based on it's voting history

1980: Reagan + 28
1984: Reagan + 36
1988: Bush + 22
1992: Bush + 5
1996: Dole + 11
2000: Bush + 18
2004: Bush + 12
2008: Obama + 3
2012: Romney + 6
2016: Trump + 3
2020: Biden + 5

I'm guessing a county in the Upper-Midwest with a population that's about 90% white, that was previously rural but is either in the exurbs of a major city or has a growing small city of its own.

And for the next county:

1960: Kennedy +34.3
1964: Johnson +45.4
1968: Humphrey +23.8
1972: Nixon +8.4
1976: Carter +20.7
1980: Reagan +0.1
1984: Reagan +0.4
1988: Dukakis +29.1
1992: Clinton +27.7
1996: Clinton +24.1
2000: Bush +6.2
2004: Bush +18.1
2008: McCain +8.0
2012: Romney +37.2
2016: Trump +44.5
2020: Trump +45.9

Would've been so much cooler had Carter in '80 and Mondale had won it, but any guesses?

It sounds like somewhere in Coal Country that is over 95% white and less than 20% have bachelor's degree or higher. My county was Leelanau, MI.

Would agree, expect the 2008 swing doesn't add up...most counties in coal county actually swung pretty hard rightward in 2008, not leftward.

Giving a Southern Illinois/Indiana vibe.

Midwestern but semi-suburban (if it were rural I'd expect a larger rightward shift).

I'm going to say either a rural area in New England, or a semi-suburban part of NY. Pretty white either way.

You were right about my county, which was Ontario, NY. I'd say your county would be in Utah, with a sizable Mormon population, but one that was nowhere near majority status in that county. Your county would be whiter than the national average

It actually was very close! It was Burlington County NJ. Technically Philly suburbs but NYC is pretty much right there. Good job.
