Yeah, not surprising...The seat was +3 Trump lol. He's likely consolidating the last of the white vote there (rural white Georgia has more White Dems then rural MS or Louisiana).
tho it is an R-internal...Prollay 52-46% Trump.
Rural White SW georgia is just as polarized as MS, or just southern Georgia. Central Georgia has Atlanta which has a decent number of liberal whites and northern Georgia has almost no minorities which depolarizes it enough for Democrats to get into the upper teens or low 20's with whites.
Not as much until recently actually. Carter got 20-25% of rural SW Georgia Whites. So did John Kerry.
Look at a county like Quitman. 54-44 Trump but was historically Democrat. the 54-44 margin for Trump mirrors the exact white-black divide (Obama won 54-45) so yes white rural vote in Georgia HAS dropped from like 15% to nearly zero.
We have vote by race in Georgia too by registration.
