Dodge County's economy is anchored in agriculture and small manufacturing, and its largely rural, white, non-college electorate has delivered Republican presidential margins above 30 points in recent cycles.
The Republican margin in Dodge County reached its widest at sixty-two points in 1920. The margin in 2024 was thirty-three points, in line with the county's deep historical pattern.
Dodge County's loyalty is rooted in its place. Median household income of $75,929, a 88% non-Hispanic-white share, and a population of 88,742 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 Gage County and Jackson County.
