Simpson County's electorate has shifted sharply toward Republican presidential candidates over the past two decades despite a Black population share near 40%, reflecting a broader realignment across rural Mississippi that has compressed Democratic performance even in historically competitive counties.
The Democratic margin here reached ninety-seven points in 1940. Between 2020 and 2024 the county moved six points toward the Republican candidate; the 2024 margin was thirty-seven 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 $56,381 and a 20% poverty rate. The county's voting pattern over the last decade is most similar to that of Hancock County and Madison County.
