Hamblen County, anchored by Morristown in the upper East Tennessee valley, has delivered lopsided Republican presidential margins for decades, with 2024's R+58.9 result reflecting the deep GOP alignment typical of small Appalachian manufacturing communities.
The Democratic margin in Hamblen County peaked at twenty points in 1912. By 1980 the county had flipped, voting Republican for the first time in many years. The 2024 margin was fifty-nine points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Hamblen County's median household income of $55,454 sits well below state and national norms, and 18% 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 Jefferson County and Greene County.
