Branch County, anchored by Coldwater, posts presidential margins that routinely exceed 40 points Republican — an outlier even within a state where rural counties trend heavily red. Its manufacturing and agricultural base has tracked rightward for more than a decade.
The Republican margin in Branch County reached its widest at fifty points in 1928. The margin in 2024 was forty-two points, in line with the county's deep historical pattern.
Branch County's loyalty is rooted in its place. Median household income of $63,724, a 88% non-Hispanic-white share, and a population of 45,300 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 Osceola County and Kalkaska County.
