Shelby County, anchored by the small city of Sidney, delivered an R+64.8 margin in 2024 — among the widest gaps in the state — reflecting the deep rural and small-town conservative consolidation that has reshaped Ohio's political map over the past decade.

The Republican margin in Shelby County reached its widest at sixty-five points in 2024. The margin in 2024 was sixty-five points, in line with the county's deep historical pattern.

Shelby County's loyalty is rooted in its place. Median household income of $73,978, a 92% non-Hispanic-white share, and a population of 47,929 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 Darke County and Appomattox County.
