Juneau County's sparse population — spread across dairy farms and Central Sands wetlands — reflects a broader rural Wisconsin pattern of accelerating Republican presidential margins, reaching R+32 in 2024.
The Republican margin in Juneau County reached its widest at sixty-seven points in 1920. The margin in 2024 was thirty-two points, in line with the county's deep historical pattern.
Juneau County's loyalty is rooted in its place. Median household income of $67,270, a 88% non-Hispanic-white share, and a population of 26,689 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 Shiawassee County and Marquette County.
