Cape May's small permanent population swells dramatically each summer with visitors and part-time residents, but its registered electorate has delivered Republican presidential margins above 15 points in every cycle since 2008.
The Republican margin in Cape May County reached its widest at fifty-three points in 1928. The margin in 2024 was nineteen points, in line with the county's deep historical pattern.
Cape May County's loyalty is rooted in its place. Median household income of $91,128, a 85% non-Hispanic-white share, and a population of 94,941 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 Manatee County and Brevard County.
