Clinton County delivered an R+76.4 margin in 2024, placing it among the most decisively one-sided counties in the state. Its small, rural population of under 10,000 reflects the broader demographic shift that has reshaped Appalachian Kentucky over the past two decades.
The Republican margin in Clinton County reached its widest at seventy-eight points in 1928. The margin in 2024 was seventy-six points, in line with the county's deep historical pattern.
Clinton County's loyalty is rooted in its place. Median household income of $44,844, a 94% non-Hispanic-white share, and a population of 9,202 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 Russell County and Garfield County.
