Mamdani Primary Test

New York’s primaries are testing Mayor Zohran Mamdani’s political influence months after his November 2025 victory, with three of his endorsed candidates competing in high-profile Democratic congressional races in New York City. Brad Lander in the 10th Congressional District and other Mamdani-backed challengers are seeking to defeat more establishment-aligned Democrats, turning the contests into an early measure of the party’s ideological direction. The races unfold alongside primaries in Maryland and Utah and runoffs in South Carolina, where endorsements from figures including Donald Trump also face voter judgment. Results in New York could shape Democratic power dynamics in Congress and preview broader intraparty fights ahead of future national elections.
