Calhoun County's R+46.7 presidential margin in 2024 places it among Iowa's most lopsided rural counties, reflecting a broader pattern of small-population agricultural communities shifting decisively away from competitive voting over the past decade.

The Republican margin in Calhoun County reached its widest at fifty-five points in 1920. The margin in 2024 was forty-seven points, in line with the county's deep historical pattern.

Calhoun County's loyalty is rooted in its place. Median household income of $64,964, a 92% non-Hispanic-white share, and a population of 9,803 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 Nobles County and Adair County.
