Madison County anchors the Elkhorn River valley in northeast Nebraska, where a largely rural, agricultural electorate has delivered Republican presidential candidates margins exceeding 50 points in recent cycles.
The Republican margin in Madison County reached its widest at sixty-nine points in 1984. The margin in 2024 was fifty-six points, in line with the county's deep historical pattern.
Madison County's loyalty is rooted in its place. Median household income of $63,128, a 80% non-Hispanic-white share, and a population of 35,532 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 Kosciusko County and Augusta County.
