How did most racist white southerners vote in every election?

Truman won most of the white vote in 1948

FYI : Carter did much much better in the rural south than he did in the suburban south and did very well in Wallace 68 counties

1968:

1980:

It is very intriguing to this day for me how much on a county level Wallace utterly decimated Humphrey and Nixon in the south.  If he picked up even two or three more southern states, he probably would have actually won more counties nationwide than Humphrey did, a feat he already came extremely close to doing

I'll just say they continued voting Democrat for longer than people here would believe. The strongest areas for Thurmond and Wallace in the south were some of the last counties to flip Republican, many of them took until after Bill Clinton. There's counties in northern Alabama that voted for Gore and against interracial marriage in 2000.

Could there be some counties that have not fully flipped yet
