Divide County sits in North Dakota's northwest corner along the Saskatchewan border, where a sparse, agriculture-dependent population has delivered Republican presidential margins exceeding 50 points in multiple consecutive cycles.
The Republican margin in Divide County reached its widest at sixty-five points in 1920. The margin in 2024 was fifty-five points, in line with the county's deep historical pattern.
Divide County's loyalty is rooted in its place. Median household income of $91,852, a 90% non-Hispanic-white share, and a population of 2,167 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 Pocahontas County and Daviess County.
