Greenwood County sits in South Carolina's textile-belt Piedmont, where a mix of small-city residents and rural voters has produced consistent 20-to-30-point Republican presidential margins over the past several election cycles.
The Democratic margin in Greenwood County peaked at 100 points in 1904. By 1984 the county had flipped, voting Republican for the first time in many years. The 2024 margin was twenty-nine points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Greenwood County's median household income of $52,830 sits well below state and national norms, and 15% 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 Franklin County and Wayne County.
