The Bronx delivers some of the widest presidential margins of any county in the U.S., anchored by a majority-Latino population and dense concentrations of public-housing residents whose turnout patterns shape citywide Democratic primaries as much as general elections.
The Democratic margin in Bronx County reached its widest at eighty-three points in 2012. The margin in 2024 was forty-five points — still decisive.
Bronx County's loyalty is rooted in its place. Median household income of $48,676, a 13% non-Hispanic-white share, and a population of 1,404,779 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 Kings County and Queens County.
