Madison County's rugged Appalachian terrain and small-town economy have consistently produced lopsided Republican margins, with the 2024 presidential result landing at R+23.4 in a county of fewer than 20,000 residents.
The Republican margin in Madison County reached its widest at sixty-three points in 1928. The margin in 2024 was twenty-three points, in line with the county's deep historical pattern.
Madison County's loyalty is rooted in its place. Median household income of $58,531, a 92% non-Hispanic-white share, and a population of 21,867 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 Kingsbury County and Haywood County.
