Newaygo's sparse population, concentrated in small towns and forested townships along the Muskegon River, has produced some of Michigan's widest presidential margins — R+42.8 in 2024 — making it a reliable anchor in Republican statewide coalition math.
The Republican margin in Newaygo County reached its widest at sixty-seven points in 1928. The margin in 2024 was forty-three points, in line with the county's deep historical pattern.
Newaygo County's loyalty is rooted in its place. Median household income of $63,304, a 88% non-Hispanic-white share, and a population of 50,792 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 Sanilac County and Columbia County.
