Marengo sits in Alabama's Black Belt, where African American majorities once anchored large Democratic margins. By 2024 that advantage had narrowed to single digits, reflecting a realignment reshaping rural counties across the region.
The Democratic margin here reached ninety-seven points in 1916. Between 2020 and 2024 the county moved five points toward the Republican candidate; the 2024 margin was four 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 $43,825 and a 22% poverty rate. The county's voting pattern over the last decade is most similar to that of Burke County and Tensas Parish.
