Williamsburg County's D+21.7 margin in 2024 stands out sharply in a state that trended heavily Republican statewide. A majority-Black population anchors the county's consistent Democratic lean across federal and statewide races.

The Democratic margin in Williamsburg County peaked at 100 points in 1936. By 1976 the county had flipped, voting Republican for the first time in many years. The 2024 margin was twenty-two points, the most Democratic-leaning result in the county's modern history.

The economic context is the key. Williamsburg County's median household income of $46,213 sits well below state and national norms, and 23% 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 Orangeburg County and Lee County.
