Grant County's sparse, ranch-dominated landscape anchors a political alignment that has delivered Republican presidential margins exceeding 60 points in recent cycles, making it among the most lopsided rural counties in North Dakota.
The Republican margin in Grant County reached its widest at seventy-two points in 1920. The margin in 2024 was sixty-seven points, in line with the county's deep historical pattern.
Grant County's loyalty is rooted in its place. Median household income of $57,875, a 92% non-Hispanic-white share, and a population of 2,269 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 Liberty County and Dickey County.
