Once anchored by copper mining and a polyglot immigrant workforce, Houghton County has moved steadily toward Republican margins over recent cycles, with 2024's R+17 reflecting broader rural U.P. realignment rather than any single-election swing.
The Republican margin in Houghton County reached its widest at seventy-seven points in 1924. The margin in 2024 was seventeen points, in line with the county's deep historical pattern.
Houghton County's loyalty is rooted in its place. Median household income of $58,899, a 92% non-Hispanic-white share, and a population of 37,693 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 Del Norte County and Ferry County.
