This sparsely populated Appalachian county in northeastern Tennessee recorded an R+79.8 presidential margin in 2024, placing it among the most one-sided results in the state. Coal-era economic geography and a predominantly white, rural population shape its consistently uniform voting pattern.
The Republican margin in Scott County reached its widest at eighty-three points in 1928. The margin in 2024 was eighty points, in line with the county's deep historical pattern.
Scott County's loyalty is rooted in its place. Median household income of $44,711, a 97% non-Hispanic-white share, and a population of 22,113 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 Hardin County and Union County.
