New York Mayor Zohran Mamdani endorsed three candidates challenging incumbent lawmakers, putting his influence and political judgment on the line. The races could help shape the city’s congressional delegation and the direction of its left-wing politics.
Mamdani endorsed Brad Lander against Rep. Dan Goldman, Claire Valdez against Antonio Reynoso, and Darializa Avila Chevalier against Rep. Adriano Espaillat. He promoted the candidates in an ad and said they would fight for working New Yorkers, protect immigrant communities and make the city more affordable. The article describes the contests as a struggle over the future of the left, with the Israeli-Palestinian conflict a central issue.
The article reports that Mamdani reversed a private commitment to support Espaillat, while his campaign did not comment on the reported agreement. Espaillat, Goldman and retiring Rep. Nydia Velázquez said they respected Mamdani’s decision or emphasized the importance of working with federal partners. Avila Chevalier addressed her past social media posts and comments about a protest, while Valdez described her political approach and support for Mamdani.
