Despite the University of Alabama anchoring a large student and faculty population in Tuscaloosa, Republican presidential candidates have carried the county by double digits in every recent cycle, reflecting the surrounding rural and suburban electorate's conservative lean.
The shift began with civil rights. 1980 marked the realignment in Tuscaloosa County, by a two points margin. The Republican margin reached its widest at sixty-nine points in 1964. The 2024 margin was twenty points.
The political shift has tracked, in Tuscaloosa County, the political shift of the South more broadly. A 60% non-Hispanic-white share, a median household income of $66,231, and a 17% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Whitfield County and Warren County.
