Carroll County, nestled in Virginia's southwestern corner along the Blue Ridge foothills, recorded an R+63.3 margin in 2024—among the steepest presidential tilts in the state—reflecting a rural, working-class electorate that has shifted sharply over the past two decades.
The Republican margin in Carroll County reached its widest at sixty-three points in 2024. The margin in 2024 was sixty-three points, in line with the county's deep historical pattern.
Carroll County's loyalty is rooted in its place. Median household income of $54,484, a 94% non-Hispanic-white share, and a population of 29,157 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Franklin County and Wythe County.
