Wayne County's mix of small manufacturing towns and agricultural land along Lake Ontario has produced a Republican presidential margin that widened by roughly 10 points between 2012 and 2024, making it one of the sharper swing stories in Upstate New York.
The Republican margin in Wayne County reached its widest at fifty-nine points in 1956. The margin in 2024 was twenty-three points, in line with the county's deep historical pattern.
Wayne County's loyalty is rooted in its place. Median household income of $74,506, a 88% non-Hispanic-white share, and a population of 90,929 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Livingston County and Steuben County.
