Alamance has trended steadily toward Republican margins over the past decade even as Burlington's metro fringe draws new residents, making it a reliable indicator of how working-class Piedmont communities respond to economic and demographic shifts.
The shift began with civil rights. 2004 marked the realignment in Alamance County, by a twenty-three points margin. The Republican margin reached its widest at fifty-one points in 1972. The 2024 margin was eight points.
The political shift has tracked, in Alamance County, the political shift of the South more broadly. A 60% non-Hispanic-white share, a median household income of $65,651, and a 13% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Cabarrus County and Wayne County.
