Cavalier County sits along the Canadian border in northeastern North Dakota, where agriculture dominates the economy and a shrinking, homogeneous population has driven presidential margins to near-supermajority levels for over a decade.
The Republican margin in Cavalier County reached its widest at fifty-nine points in 1920. The margin in 2024 was forty-nine points, in line with the county's deep historical pattern.
Cavalier County's loyalty is rooted in its place. Median household income of $69,531, a 92% non-Hispanic-white share, and a population of 3,633 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 Pembina County and Cass County.
