A Democratic primary in New York’s 13th Congressional District unseats Rep. Adriano Espaillat, according to election projections and reporting. Multiple outlets report that Darializa Avila Chevalier, described as a socialist and backed by New York City Mayor Zohran Mamdani, defeats the five-term incumbent Espaillat in Tuesday’s Democratic primary. The Hill and Fox News both characterize the race as a test of influence for Mayor Mamdani within New York City politics, and both credit Chevalier’s support network for the challenger’s victory. Fox News also highlights Chevalier’s past rhetoric as part of its framing of the win, while The Hill focuses more on the electoral outcome and the broader significance for the city’s socialist movement. Despite differences in emphasis, both sources agree on the central result: Chevalier defeats Espaillat in the Democratic primary for the seat. The primary sets up who will represent the district in the general election, though neither source provided additional details on turnout or final vote totals in the excerpts provided.
