Hart County's R+60 margin in 2024 places it among Kentucky's most one-sided presidential results, reflecting the broader rural realignment that has reshaped the western Pennyroyal and Knobs region over the past two decades.
The Democratic margin in Hart County peaked at twenty-nine points in 1912. By 1996 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Hart County's median household income of $52,285 sits well below state and national norms, and 19% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Wirt County and Texas County.
