Sac County's population has declined steadily for decades as agriculture consolidated, leaving a small, older, and overwhelmingly rural electorate that has drifted toward increasingly wide Republican margins in presidential races.
The Republican margin in Sac County reached its widest at fifty-nine points in 1920. The margin in 2024 was fifty-one points, in line with the county's deep historical pattern.
Sac County's loyalty is rooted in its place. Median household income of $73,838, a 93% non-Hispanic-white share, and a population of 9,689 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 Hancock County and Cherokee County.
