Tazewell County, anchored by the coalfield economy of Southwest Virginia, recorded an R+68.9 presidential margin in 2024—among the most lopsided results in the state and a signal of how sharply rural Appalachian voters have realigned over the past two decades.
The Democratic margin in Tazewell County peaked at twenty points in 1936. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-nine points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Tazewell County's median household income of $47,313 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 Mercer County and Wise County.
