New York Assemblyman Zohran Mamdani, a socialist, and City Comptroller Brad Lander endorsed each other on Friday, the day after the final debate for the New York City mayoral Democratic primary, in hopes that they can beat front-runner former Gov.

With little over one week left until the mayoral primary, Zohran Mamdani’s momentum against Andrew Cuomo is drawing widespread opposition to stop him from winning the Democratic nomination and likely City Hall.

With a week remaining in a tightening mayoral primary race, wealthy supporters of Andrew Cuomo are pouring millions of dollars into efforts to boost his campaign and halt the momentum of his chief rival, Zohran Mamdani. Allies of the socialist assemblyman are mounting their own comparatively modest effort to topple the front-runner.
