Racine County anchors Wisconsin's southeastern industrial lakeshore, where a working-class electorate once reliably Democratic has shifted steadily rightward over the past decade, moving from a 2012 Obama win to a 6-point Republican margin in 2024.
The Democratic margin in Racine County has rarely exceeded thirty-six points in modern history; the Republican margin has rarely exceeded fifty-four points. 2024 delivered the county to the Republican candidate by six points.
Racine County's demographics resemble the country more than they resemble most counties. A 72% non-Hispanic-white share, a 10% poverty rate, and a median household income of $78,096 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Hill County and Marshall County.
