Henry County anchors Virginia's Southside textile and furniture corridor, and its electorate has shifted steadily rightward over the past decade as rural working-class realignment accelerated, producing a 2024 presidential margin of R+32.8.
The Democratic margin in Henry County peaked at fifty-nine points in 1936. By 1996 the county had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-three points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Henry County's median household income of $50,760 sits well below state and national norms, and 16% 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 Luce County and Osceola County.
