Three candidates backed by New York City Mayor Zohran Mamdani won their Democratic primaries, a result the article presents as evidence of his growing influence and a challenge to party leaders. The contest between Brad Lander and Rep. Dan Goldman also highlighted disputes over corporate influence and Israel.
Claire Valdez, Brad Lander and Darializa Avila Chevalier won primaries in New York’s 7th, 10th and 13th districts after receiving Mamdani’s endorsements. Democratic campaign veteran Adam Carlson called the results a test of whether Mamdani’s endorsements and campaigning could translate when he was not on the ballot, and said he had asserted himself as a new power broker. The article argues the results could signal a broader shift in the Democratic Party.
In the 10th District contest, Lander defeated Goldman, whose supporters included Nancy Pelosi, Hakeem Jeffries and Gov. Kathy Hochul. Lander criticized corporate influence and Goldman’s approach to Israel; Goldman disputed Lander’s characterization of his record and criticized his campaign strategy. The article also notes that Jeffries may face a more ideologically left-leaning House Democratic caucus if Democrats retake the chamber.

19 OUTLETSOutlets agree that Brad Lander, endorsed by New York City Mayor Zohran Mamdani, defeated Rep. Daniel Goldman in the 10th District Democratic primary; other Mamdani-backed candidates also won New York congressional primaries. Left-leaning outlets present the results as progressive victories over party establishment politics, with particular attention to pro-Israel lobbying. Center outlets largely frame the wins as a test of Mamdani’s influence and Democratic Party direction, while some focus on Israel-related politics. Right-leaning outlets emphasize the gains as a challenge to Democratic leaders and scrutinize the candidates’ socialist labels and positions on Israel.
