Brad Lander holds a commanding lead in the June 23 Democratic primary for New York’s 10th Congressional District, reflecting strong polling margins and endorsements from progressive figures including Mayor Zohran Mamdani. Incumbent Dan Goldman maintains institutional backing from Governor Kathy Hochul and party leaders but trails in recent surveys of likely primary voters. The race centers on differences in fundraising approaches, foreign policy positions, and alignment with local Democratic priorities in the Lower Manhattan and Brooklyn portions of the district. Late shifts could occur if Goldman narrows the gap through targeted outreach or if turnout patterns among key voting blocs favor the incumbent in the final weeks before the primary.
