Tucked against the North Carolina border in the Smoky Mountain foothills, Cocke County delivered a 68-point Republican presidential margin in 2024, reflecting the deep rural conservatism that defines much of Appalachian East Tennessee.
The Republican margin in Cocke County reached its widest at seventy-three points in 1972. The margin in 2024 was sixty-eight points, in line with the county's deep historical pattern.
Cocke County's loyalty is rooted in its place. Median household income of $48,016, a 93% non-Hispanic-white share, and a population of 36,813 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 Henderson County and Greene County.
