Chase County's cattle-ranch economy and sparse settlement—roughly two people per square mile—have made it one of the most reliably Republican counties in Kansas, with 2024 margins exceeding 50 points.
The Republican margin in Chase County reached its widest at fifty-six points in 1972. The margin in 2024 was fifty-one points, in line with the county's deep historical pattern.
Chase County's loyalty is rooted in its place. Median household income of $56,484, a 89% non-Hispanic-white share, and a population of 2,561 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 Kay County and Chautauqua County.
