Jackson County's R+58.1 margin in 2024 places it among the most one-sided presidential results in the state, reflecting the deep-red realignment that has reshaped southeastern Ohio's rural, Appalachian-edge communities over the past decade.
The Democratic margin in Jackson County peaked at eighteen points in 1964. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was fifty-eight points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Jackson County's median household income of $57,106 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 Noble County and Gallia County.
