Bonneville delivered an R+45.6 margin in 2024, consistent with its pattern as a heavily LDS, exurban county centered on Idaho Falls — a regional hub whose growth has not meaningfully shifted its partisan composition.
The Republican margin in Bonneville County reached its widest at sixty-six points in 1984. The margin in 2024 was forty-five points, in line with the county's deep historical pattern.
Bonneville County's loyalty is rooted in its place. Median household income of $79,068, a 84% non-Hispanic-white share, and a population of 129,523 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 Midland County and Washington County.
