Marlboro County's electorate reflects the demographic tension common to majority-Black rural counties in the Pee Dee region, where Democratic margins have compressed steadily over successive presidential cycles despite a Black share of the population near 50%.
The Democratic margin here reached 100 points in 1912. Between 2020 and 2024 the county moved nine points toward the Republican candidate; the 2024 margin was two points. The recent movement, modest against a deep Democratic baseline, mirrors a broader rightward drift across the Black Belt.
The economic context is part of the story: a median household income of $34,301 and a 29% poverty rate. The county's voting pattern over the last decade is most similar to that of Hampton County and Surry County.
