Fauquier sits at the outer edge of Northern Virginia's commuter belt, where working farms and estate properties define a landscape distinct from the dense suburbs closer to Washington — and its R+21.7 presidential margin reflects that rural-exurban character.
The shift began with civil rights. 1968 marked the realignment in Fauquier County, by a eleven points margin. The Republican margin reached its widest at forty-three points in 1984. The 2024 margin was twenty-two points.
The political shift has tracked, in Fauquier County, the political shift of the South more broadly. A 80% non-Hispanic-white share, a median household income of $130,189, and a 7% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Union County and Aiken County.
