St. Johns sits south of Jacksonville along the St. Augustine coast and has nearly doubled in population since 2010, drawing suburban and exurban migrants who have reinforced its already wide Republican presidential margins.

The shift began with civil rights. 1980 marked the realignment in St. Johns County, by a twenty-three points margin. The Republican margin reached its widest at fifty-five points in 1972. The 2024 margin was thirty-one points.

The political shift has tracked, in St. Johns County, the political shift of the South more broadly. A 79% non-Hispanic-white share, a median household income of $109,839, and a 7% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Okaloosa County and Santa Rosa County.
