Kidder County's sparse, agriculture-driven population of roughly 2,700 has delivered Republican presidential margins above 60 points in recent cycles, making it a reliable anchor of North Dakota's deep-red interior.
The Republican margin in Kidder County reached its widest at seventy-seven points in 1904. The margin in 2024 was sixty-four points, in line with the county's deep historical pattern.
Kidder County's loyalty is rooted in its place. Median household income of $65,610, a 96% non-Hispanic-white share, and a population of 2,377 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 McKenzie County and Oliver County.
