Gloucester sits on a peninsula between the York and Piankatank rivers, with an economy rooted in commercial fishing and commuter ties to Hampton Roads. Its presidential margins have exceeded 35 points Republican in recent cycles, reflecting the broader rural Tidewater pattern.
The shift began with civil rights. 1980 marked the realignment in Gloucester County, by a fourteen points margin. The Republican margin reached its widest at forty-six points in 1972. The 2024 margin was thirty-eight points.
The political shift has tracked, in Gloucester County, the political shift of the South more broadly. A 83% non-Hispanic-white share, a median household income of $84,306, and a 5% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Mathews County and Middlesex County.
