Thomas County anchors the Florida border in Georgia's agricultural south, where a largely rural electorate has delivered Republican presidential margins above 20 points in each of the last four cycles.
The shift began with civil rights. 1984 marked the realignment in Thomas County, by a twenty-three points margin. The Republican margin reached its widest at fifty-one points in 1972. The 2024 margin was twenty-four points.
The political shift has tracked, in Thomas County, the political shift of the South more broadly. A 58% non-Hispanic-white share, a median household income of $60,736, and a 18% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Ouachita Parish and Bulloch County.
