Nowadays, whites in southern US tend to go massively GOP, often north of 70% and some over 80%. For South to make it simple, I am referring to former confederate states from US civil war, so what would be some areas be it cities, or counties where Biden and Democrats of recent won white vote. Ones I can think of are:
- Austin metro area
- Dallas proper, but not suburbs
- New Orleans
- Springdale, Arkansas (one of few cities in Arkansas where Biden likely won white vote)
- Nashville
- Northern Virginia
- Charlottesville
- Buncombe, Orange, Durham, Wake and possibly Mecklenburg county in North Carolina
- Inner Atlanta metro area (Fulton, DeKalb and Clayton counties, counties beyond Biden won but not white vote)
- Athens, Georgia
- Alachua county for sure and possibly Leon, Orange, Broward, and Miami-Dade in Florida but Alachua is only one I am certain Biden won there.
Mississippi and Alabama appear to be two states where GOP wins white vote everywhere. In case of South Carolina, Trump probably won white vote in Charleston and Richland counties, but Biden narrowly in Charleston and Columbia proper.
I'm leery about Dallas, because it's only Biden+41, despite having quite a small proportion of white voters. Moreover the southern part of the city (bordering Kaufman County) is heavily African-American and votes 85-95% D, so that's probably a big factor driving up the Democratic margin in the city.
Also not sure about Leon (which I'd guess is pretty racially polarized - Tallahassee isn't a particularly large city with a growing population, so I'm guessing the Democratic votes are coming from the black population that's historically lived there rather than white transplants) or Orange (which is very, very racially diverse and not all that Democratic - Biden barely cracked 60%) Counties in Florida.
