Sanpete County, a rural stretch of central Utah anchored by small LDS-majority towns, recorded an R+66.7 margin in 2024 — placing it among the state's most one-sided jurisdictions and reflecting the deep Republican lean of agrarian Intermountain West communities.
The Republican margin in Sanpete County reached its widest at seventy-eight points in 2012. The margin in 2024 was sixty-eight points, in line with the county's deep historical pattern.
Sanpete County's loyalty is rooted in its place. Median household income of $70,083, a 86% non-Hispanic-white share, and a population of 29,719 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 Uintah County and Franklin County.
