This sparsely populated southwest Kansas county, anchored by the small city of Sublette, recorded a 64.5-point Republican presidential margin in 2024 — typical of the region's deep-rooted conservative voting patterns in dryland farming communities.
The Republican margin in Haskell County reached its widest at seventy-one points in 2004. The margin in 2024 was sixty-four points, in line with the county's deep historical pattern.
Haskell County's loyalty is rooted in its place. Median household income of $66,162, a 71% non-Hispanic-white share, and a population of 3,641 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 Stanton County and Glasscock County.
