Sussex is one of Virginia's least populous counties, yet its majority-Black electorate has made it a consistent Democratic-leaning outlier in a Southside region that otherwise tilts sharply Republican, with 2024's D+4.4 margin continuing that pattern.
The Democratic margin in Sussex County reached its widest at seventy-five points in 1936. The margin in 2024 was four points — still decisive.
Sussex County's loyalty is rooted in its place. Median household income of $63,530, a 41% non-Hispanic-white share, and a population of 10,765 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Brunswick County and Athens County.
