Hamilton County sits at the Colorado border in the sparsely settled western Kansas shortgrass prairie, where a small, agriculture-dependent population has produced some of the widest Republican presidential margins in the state over the last decade.
The Republican margin in Hamilton County reached its widest at sixty-seven points in 2016. The margin in 2024 was sixty-six points, in line with the county's deep historical pattern.
Hamilton County's loyalty is rooted in its place. Median household income of $70,250, a 63% non-Hispanic-white share, and a population of 2,471 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 Hodgeman County and Cheyenne County.
