Zohran Mamdani's Picks Win New York Democratic House Primaries

Mayor Zohran Mamdani’s endorsements carried three progressive candidates to decisive victories in New York’s June 23 Democratic primary for the U.S. House. Former city comptroller Brad Lander defeated incumbent Rep. Dan Goldman in the 10th District, state Assemblywoman Claire Valdez won the open 7th District seat, and community organizer Darializa Avila Chevalier unseated five‑term Rep. Adriano Espaillat in the 13th District. All three candidates ran on a platform that emphasized affordable housing, opposition to U.S. military aid for Israel, and broader “working‑people” priorities, a strategy Mamdani described as a shift in the balance of power. Their wins ousted two sitting Democrats and added two Democratic Socialists of America‑backed members to the expected slate of general‑election victors, doubling the socialist‑leaning caucus in Congress.

The outcomes dealt a blow to the pro‑Israel lobbying establishment, with AIPAC‑supported incumbents losing and Republican leaders mocking the “socialist” turn, even sending condolence flowers to House Minority Leader Hakeem Jeffries. The sweep has energized the DSA, prompting a nationwide chapter survey for a 2028 presidential endorsement and highlighting the growing influence of left‑wing politics beyond New York City.

These results reshape the Democratic Party’s internal dynamics, strengthen Mamdani’s political clout, and signal a broader resurgence of progressive, anti‑establishment forces in American electoral politics.
