Greenbrier County anchors West Virginia's southern highlands, blending resort-town tourism near White Sulphur Springs with a broader rural population that has moved decisively toward Republican candidates in every presidential cycle since 2000.
The Democratic margin in Greenbrier County peaked at forty points in 1912. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty-two points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Greenbrier County's median household income of $48,218 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 Gilmer County and Randolph County.
