Billings County's roughly 900 residents are spread across the North Dakota Badlands, and its lopsided presidential margins reflect a rural ranching electorate where third-party or Democratic votes can be counted in the dozens.
The Republican margin in Billings County reached its widest at eighty-four points in 1920. The margin in 2024 was seventy points, in line with the county's deep historical pattern.
Billings County's loyalty is rooted in its place. Median household income of $86,806, a 95% non-Hispanic-white share, and a population of 1,024 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 Golden Valley County and Morrill County.
