Cumberland sits in Virginia's rural Piedmont with fewer than 10,000 residents, and its 2024 presidential margin of R+22.2 reflects a long-running pattern of lopsided results in low-density counties west of Richmond.
The shift began with civil rights. 1980 marked the realignment in Cumberland County, by a five points margin. The Republican margin reached its widest at twenty-seven points in 1988. The 2024 margin was twenty-two points.
The political shift has tracked, in Cumberland County, the political shift of the South more broadly. A 64% non-Hispanic-white share, a median household income of $55,325, and a 9% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Mecklenburg County and Lee County.
