Hillsdale County's 2024 presidential margin of R+51.4 places it among Michigan's most lopsided rural results, a pattern rooted in its small-town agricultural economy and minimal urban population centers.
The Republican margin in Hillsdale County reached its widest at sixty-two points in 1928. The margin in 2024 was fifty-one points, in line with the county's deep historical pattern.
Hillsdale County's loyalty is rooted in its place. Median household income of $64,242, a 93% non-Hispanic-white share, and a population of 45,654 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 Susquehanna County and Warren County.
