Unlikely, since non-white voters were probably above 25% of the GA electorate, and would be breaking extremely lopsided to Carter (more than a 60 point margin for sure). GA was within 15% in 1980.
I have to reject this claim. GA SoS records race by voter registration
and turnout:
non-whites didn't reach 25% of the electorate in GA until 2004. Unless a ton of non-whites were identifying as white when they registered (which back then would've been
very unlikely), there's no argument for them being anywhere close to 25%
in 1980.
Even before this particular metric, I was also skeptical that Carter didn't win a majority of whites in the less racially progressive states of SC & AL in 1976. After all, these county maps (
AL,
SC) basically mean that unless a large segment of white voters resided in this handful of "ancestrally-GOP" counties
in 1976, that the overwhelmingly rural white counties that all went for Carter indicate a trend.
