Staten Island (Richmond County) delivered a 29.5-point Republican margin in 2024, making it a persistent outlier within a city that votes heavily Democratic — a pattern driven by its outer-borough, homeowner-heavy demographic profile.
The Republican margin in Richmond County reached its widest at fifty-three points in 1956. The margin in 2024 was twenty-nine points, in line with the county's deep historical pattern.
Richmond County's loyalty is rooted in its place. Median household income of $98,333, a 60% non-Hispanic-white share, and a population of 494,956 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 Somerset County and Salem County.
