St. Clair County's R+34.6 margin in 2024 reflects a blue-collar lakeside corridor that has moved steadily away from its mid-century Democratic roots, driven by deindustrialization along the Port Huron waterfront and an aging, predominantly white electorate.
Across the recorded series it reached a Democratic high of 18.3 points in 1964 and a Republican high of 43.4 points in 1928. Between 2020 and 2024 the county moved 4.4 points toward the Republican candidate; the 2024 margin was 34.6 points.
A population of 160,221, a 90% non-Hispanic-white share, and a median household income of $71,270 describe the county. The county's voting pattern over the last decade is most similar to that of Iosco County and Chenango County.
