Community organizer Darializa Avila Chevalier defeated incumbent Rep. Adriano Espaillat (D-NY) in the Democratic primary for New York’s 13th Congressional District on June 23, 2026 [2].

The victory marks a significant shift in the political landscape of the district, which covers parts of the Bronx and Manhattan. The defeat of an establishment incumbent by a progressive challenger indicates a growing appetite for grassroots leadership in the region.

Chevalier, 32 [1], secured the win through a combination of a strong grassroots ground game and high-profile political backing. She was supported by New York Mayor Zohran Mamdani, whose endorsement provided a decisive advantage against Espaillat.

Reports on the outcome varied across news outlets. While some sources indicated Espaillat was projected to lose, other reports confirmed he was defeated in the primary [2].

The campaign leading up to the vote was characterized by a clash between the establishment and the progressive wing of the party. Chevalier's path to victory relied on mobilizing local organizers and leveraging the influence of Mayor Mamdani's political network.

Espaillat, who has represented the district, faced a challenger who focused on community-led initiatives and progressive policy shifts. The outcome of the June 23 [2] primary ensures that a new voice will represent the Bronx and Manhattan interests in the U.S. House of Representatives.
