St. Clair's R+64 margin in 2024 reflects the lopsided partisanship common to the Appalachian foothills east of Birmingham, where population growth from suburban spillover has done little to shift the county's deeply Republican baseline.
The Republican margin here reached seventy-one points in 1964. The 2024 margin was sixty-four points.
A population of 94,166, a 84% non-Hispanic-white share, and a median household income of $77,463 describe the county. The county's voting pattern over the last decade is most similar to that of Washington County and Nassau County.
