Glynn County anchors Georgia's Golden Isles tourism economy while hosting one of the Southeast's busiest container terminals, a combination that has kept its presidential margins consistently Republican by mid-to-high double digits over the past decade.
The shift began with civil rights. 1984 marked the realignment in Glynn County, by a twenty-eight points margin. The Republican margin reached its widest at fifty-two points in 1972. The 2024 margin was twenty-six points.
The political shift has tracked, in Glynn County, the political shift of the South more broadly. A 64% non-Hispanic-white share, a median household income of $69,799, and a 16% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Otero County and Boone County.
