Mamdani-Backed Candidates Win Three New York Congressional Primaries

Three candidates endorsed by New York City Mayor Zohran Mamdani won Democratic congressional primaries in New York on Tuesday, defeating two sitting members of Congress. The victories give the mayor a clean sweep across the three races he entered. With 90 percent of ballots counted in one contest, the leading candidate received 65.8 percent of the vote.

10th District, former New York City comptroller Brad Lander defeated incumbent representative Dan Goldman. Lander also received an endorsement from a Vermont senator. With 92 percent of ballots counted, state Assemblywoman Claire Valdez held a 20-point lead over Brooklyn Borough President Antonio Reynoso.

In New York's 13th District, former Mamdani campaign staffer Darializa Avila Chevalier defeated a five-term incumbent by a 3.5-point margin.

Mamdani addressed supporters after the races were called. He drew a parallel to his own mayoral victory last year.

“What you all have shown this evening, whether for state assembly, state senate, or Congress, is that a year ago it was not the end of a political movement.”

New York’s DSA branch also saw success in state legislative primaries, with seven of its eight endorsed candidates on course to win and raise its numbers in Albany to 14 from nine. ” The three winners campaigned on anti-Israel platforms and called for limits on U.S. arms sales to Israel.

Valdez also backed seizure of property from landlords, while Chevalier said she does not believe criminal illegal aliens should be deported.
