Mobile County's port economy and sizable Black population—roughly 35% of residents—create a more competitive baseline than most of rural Alabama, yet the county still delivered a 16-point Republican margin in 2024.
The shift began with civil rights. 1972 marked the realignment in Mobile County, by a forty-nine points margin. The Republican margin reached its widest at seventy-one points in 1964. The 2024 margin was sixteen points.
The political shift has tracked, in Mobile County, the political shift of the South more broadly. A 56% non-Hispanic-white share, a median household income of $58,880, and a 16% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Scott County and Culpeper County.
