Hampshire County's R+62.5 margin in 2024 reflects a broader Appalachian shift toward lopsided Republican dominance; its sparse population and rugged South Branch Potomac terrain define an electorate where Democratic competitiveness has largely disappeared over two decades.
The Republican margin in Hampshire 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.
Hampshire County's loyalty is rooted in its place. Median household income of $63,116, a 94% non-Hispanic-white share, and a population of 23,465 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 Clarion County and Martin County.
