A slate of candidates backed by Zohran Mamdani has won democratic primaries in New York, unseating two incumbent members of Congress. The winners include Brad Lander, Claire Valdez, and Darializa Avila Chevalier, while Jack Schlossberg, a member of the Kennedy family, lost his bid. The outcomes are seen as a sign of the mood among some Democratic voters ahead of the midterms, with some interpreting the results as a show of power by Mamdani and a shift towards progressive candidates.
