Tucked into Idaho's panhandle along the Canadian border, Boundary County delivered one of the state's widest presidential margins in 2024, reflecting the deep-red alignment common to rural, timber-economy communities in the inland Northwest.

The Republican margin in Boundary County reached its widest at sixty-five points in 2024. The margin in 2024 was sixty-five points, in line with the county's deep historical pattern.

Boundary County's loyalty is rooted in its place. Median household income of $67,237, a 83% non-Hispanic-white share, and a population of 13,172 together describe a community whose political habits are deeply settled.
