New York mayor-elect Zohran Mamdani endorsed Brad Lander in his Democratic primary challenge to Representative Dan Goldman. The story describes the endorsement as a boost for Lander’s campaign and notes support from other progressive figures.
Mamdani, who worked with Lander during his mayoral campaign, said he was proud to support Lander in the race for New York’s 10th Congressional District. Lander welcomed the endorsement. The article also reports that Bernie Sanders, Elizabeth Warren, the Working Families Party and other left-wing figures support Lander.
The article notes that Mamdani carried Goldman’s district in the Democratic mayoral primary, while Goldman did not endorse Mamdani in the mayoral general election. It recounts Goldman’s narrow 2022 primary win and says former challenger Yuh-Line Liou dropped out of the current race last year to avoid dividing the liberal base.
