Alfalfa County, anchored by the small city of Cherokee, reported an R+76.6 presidential margin in 2024—among the widest in a state already dominated by rural Republican supermajorities. Its sparse, wheat-farming economy has tracked closely with statewide rightward drift for decades.
The Republican margin in Alfalfa County reached its widest at seventy-seven points in 2020. The margin in 2024 was seventy-seven points, in line with the county's deep historical pattern.
Alfalfa County's loyalty is rooted in its place. Median household income of $64,615, a 82% non-Hispanic-white share, and a population of 5,696 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 Harper County and Gaines County.
