Grant County, a sparsely populated wheat-farming county on the Kansas border, recorded a 70-point Republican presidential margin in 2024 — among the widest in a state already dominated by rural red-shift.
The Republican margin in Grant County reached its widest at seventy-three points in 2020. The margin in 2024 was seventy-one points, in line with the county's deep historical pattern.
Grant County's loyalty is rooted in its place. Median household income of $60,758, a 86% non-Hispanic-white share, and a population of 4,131 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 Wheeler County and Jackson County.
