Clean sweep for Mamdani-backed candidates in New York's Democratic primary

Key Points:

• Progressive challenger Brad Lander defeated incumbent Congressman Dan Goldman in New York's 10th district primary, marking a victory for candidates backed by Democratic Socialist Mayor Zohran Mamdani amid party divisions over the Israel-Gaza war.
• Two other Mamdani-endorsed democratic socialists, Assemblywoman Claire Valdez and Darializa Avila Chevalier, won their primary races in New York's 7th and 13th districts respectively, signaling a shift to the left in the city's Democratic Party.
• Lander, who accused Israel of genocide in Gaza and was endorsed by Senator Bernie Sanders, won decisively with 65.7% of the vote, while Goldman, supported by pro-Israel groups, conceded and congratulated Lander.
• Mamdani praised the winners for their progressive visions, emphasizing a focus on working-class issues, though establishment Democrats worry these left-wing candidates may struggle with swing voters in the upcoming midterms.
• In other notable races, Jack Schlossberg, JFK’s grandson, lost in the 12th district primary, while conservative lawyer George Conway also performed poorly, highlighting the complex dynamics within New York’s Democratic primaries.
