Progressive candidates endorsed by New York City Mayor Zohran Mamdani scored a clean sweep Tuesday night in three Democratic House primaries. Brad Lander in NY-10, Claire Valdez in NY-07 and Darializa Avila Chevalier in NY-13 all advanced to the general election, where each is expected to be strongly positioned in solidly Democratic districts.
The tightest race among the three came in NY-13, where Avila Chevalier narrowly defeated five-term incumbent Rep. Adriano Espaillat, the chairman of the Congressional Hispanic Caucus. Espaillat also serves as co-chair of the House Latino-Jewish Caucus, a role that placed him at the center of increasingly heated Democratic debates over Israel and Middle East policy in New York politics.
With an estimated 88 percent of the vote counted, the race stood as follows:
