Sequatchie County sits in a narrow valley carved through the Cumberland Plateau, and its small, rural electorate has shifted decisively rightward over two decades, posting a 66-point Republican presidential margin in 2024.
The Democratic margin in Sequatchie County peaked at forty-five points in 1932. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-six points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Sequatchie County's median household income of $58,750 sits well below state and national norms, and 22% 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 Meigs County and McNairy County.
