Clarke County's 12,600 residents occupy the lower Shenandoah Valley, where low population density and agricultural land use correlate with presidential margins that have run consistently Republican by double digits across recent cycles.
The shift began with civil rights. 1968 marked the realignment in Clarke County, by a fourteen points margin. The Republican margin reached its widest at forty-two points in 1972. The 2024 margin was seventeen points.
The political shift has tracked, in Clarke County, the political shift of the South more broadly. A 84% non-Hispanic-white share, a median household income of $117,111, and a 7% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Livingston County and Lake County.
