Dawes County, anchored by Chadron in the Pine Ridge region, delivered a 47-point Republican presidential margin in 2024 — a result consistent with its sparse, ranching-dominated economy and a population that has trended steadily more Republican over the past two decades.
The Republican margin in Dawes County reached its widest at sixty-two points in 1972. The margin in 2024 was forty-seven points, in line with the county's deep historical pattern.
Dawes County's loyalty is rooted in its place. Median household income of $56,280, a 87% non-Hispanic-white share, and a population of 8,140 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 Lincoln County and Churchill County.
