Colfax County's population is roughly 40% Hispanic, a demographic composition unusual for the Great Plains, yet presidential margins have run heavily Republican — a pattern that mirrors broader rural Latino rightward shifts seen nationally in 2024.
The Republican margin in Colfax County reached its widest at fifty-three points in 1980. The margin in 2024 was fifty-one points, in line with the county's deep historical pattern.
Colfax County's loyalty is rooted in its place. Median household income of $82,530, a 51% non-Hispanic-white share, and a population of 10,641 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 Bailey County and Jackson County.
