Recent polling from early May shows Brad Lander leading incumbent Rep. Dan Goldman by a narrow margin among likely Democratic primary voters in New York’s 10th Congressional District, with endorsements from progressive leaders including Mayor Zohran Mamdani and Sen. Bernie Sanders bolstering Lander’s position. Goldman, facing this challenge ahead of the June 23 primary, has responded by committing at least $1 million of personal funds and matching incoming donations, drawing on his congressional record on issues such as immigration oversight and taxes. Minor candidates including Cameron Kasky, Alexa Avilés, and Yuh-Line Niou register minimal support. Trader consensus on these probabilities reflects Lander’s edge in fundraising momentum and voter sentiment in a district with strong progressive turnout patterns.
