Osborne County, anchored by its small agricultural seat, recorded an R+68.5 margin in 2024—among the widest in a state already dominated by rural Republican strongholds. Its shrinking population reflects broader depopulation trends across the High Plains.
Across the recorded series it reached a Democratic high of 9.3 points in 1916 and a Republican high of 69.3 points in 2020. Between 2020 and 2024 the county moved 0.8 points toward the Democratic candidate; the 2024 margin was 68.5 points.
A population of 3,452, a 92% non-Hispanic-white share, and a median household income of $63,011 describe the county. The county's voting pattern over the last decade is most similar to that of Graham County and Lincoln County.
