Carlton County's economy was long anchored by paper mills and the Fond du Lac Band of Lake Superior Chippewa, producing reliably Democratic margins. By 2024 it flipped narrowly Republican, a shift that mirrors working-class realignment across Minnesota's Iron Range corridor.
The Democratic margin in Carlton County reached its widest at fifty-five points in 1964. The margin in 2024 was three points — a notable narrowing.
Carlton County's loyalty is rooted in its place. Median household income of $80,573, a 88% non-Hispanic-white share, and a population of 36,518 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 Mahoning County and Douglas County.
