Switzerland County's small, rural population along the Ohio River has delivered Republican presidential margins above 50 points in recent cycles, reflecting a broader shift in agrarian river-bottom communities away from competitive two-party voting.
The Republican margin in Switzerland County reached its widest at fifty-seven points in 2024. The margin in 2024 was fifty-seven points, in line with the county's deep historical pattern.
Switzerland County's loyalty is rooted in its place. Median household income of $65,343, a 95% non-Hispanic-white share, and a population of 9,909 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 Taylor County and Clearwater County.
