Orleans Parish, coterminous with New Orleans, posted a D+67 margin in 2024, driven by a majority-Black electorate and a dense urban core that consistently produces some of the widest presidential margins in Louisiana.
The Democratic margin in Orleans Parish reached its widest at eighty-eight points in 1932. The margin in 2024 was sixty-seven points — still decisive.
Orleans Parish's loyalty is rooted in its place. Median household income of $56,631, a 31% non-Hispanic-white share, and a population of 371,853 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 Suffolk County and Holmes County.
