NY-10: Brad Lander set to challenge Rep. Dan Goldman from the left [View all]

NEW YORK — Brooklyn progressive Brad Lander is planning to launch his bid for Congress as soon as Wednesday, challenging Rep. Dan Goldman from the political left in a district that went big for Zohran Mamdani, three people familiar with his preparations told POLITICO.

The city comptroller is expected to open his campaign with a pivotal endorsement from Mamdani, the democratic socialist mayor-elect’s first formal nod since his November election win upended the Democratic landscape. Lander has also sought support from progressive Sens. Bernie Sanders and Elizabeth Warren, according to two people close to Lander.

Lander shot his campaign launch video, with some scenes from his Park Slope community, two people with knowledge of his operations said. And he is interviewing for the Working Families Party endorsement, four more people confirmed to POLITICO. The people looped into Lander’s plans were granted anonymity to protect a sensitive rollout process.

Lander’s entry will mark New York progressives’ boldest salvo yet in primaries to unseat more mainstream party members on the heels of Mamdani’s ascension to the helm of the country’s largest city. The fiscal wonk and Israel critic is a favorite of left-leaning voters in the liberal congressional district, which encompasses lower Manhattan and northwest Brooklyn and overlaps Lander’s former City Council district.
