New York City Mayor Zohran Mamdani endorsed Democratic Socialist Darializa Avila Chevalier on Thursday to challenge incumbent Rep. Adriano Espaillat [1].
The endorsement signals a push to shift the political direction of Upper Manhattan toward the progressive wing of the Democratic party. By backing a challenger against an established incumbent, the mayor is leveraging his office to influence the composition of the U.S. House of Representatives.
Chevalier is running in the Democratic primary for New York's 13th Congressional District [2]. The primary election is scheduled for June 23, 2026 [1].
Mamdani said the move represents his final congressional endorsement for the current cycle. He said that he wants to support a progressive and Democratic Socialist candidate to challenge the incumbent in the district [3].
The endorsement comes during a period of internal party tension in New York. While some reports indicated the mayor was considering the move, other sources confirmed the official endorsement of Chevalier [4].
Rep. Espaillat has held the seat in the 13th District, which covers parts of Upper Manhattan [5]. The entry of a mayor-backed challenger introduces a new dynamic to the race as the June primary approaches.
This move aligns with Mamdani's broader political trajectory and his commitment to the Democratic Socialist movement. The endorsement is intended to provide Chevalier with increased visibility, and political legitimacy among the city's progressive base [3].
“Mamdani said it is his final congressional endorsement.”
This endorsement reflects a strategic effort by the New York City mayor to expand the influence of the Democratic Socialist caucus within the federal government. By targeting a sitting incumbent in the 13th District, Mamdani is testing the strength of the progressive movement's ability to displace established Democratic leadership in Upper Manhattan.
