Bernie Sanders has endorsed Zohran Mamdani, a leftwing candidate running for New York City mayor, adding momentum to Mamdani’s insurgent campaign. Mamdani, a democratic socialist like Sanders, is challenging former New York governor Andrew Cuomo, who aims to revive his political career following sexual harassment allegations. Mamdani’s rise in popularity, including securing endorsements from figures like Alexandra Ocasio-Cortez, has put him neck and neck with Cuomo in recent polls.

Sanders emphasized the need for new leadership that prioritizes standing up to powerful corporate interests and advocating for the working class. In response, Mamdani expressed admiration for Sanders and pledged to emulate his dedication to fighting for the working class if elected mayor.

The Democratic primary election, using ranked-choice voting to allow voters to rank up to five candidates, is scheduled for 24 June after early voting started on 14 June. Eric Adams, the current mayor seeking re-election as an independent candidate, has faced criticism from Democrats for his ties to Donald Trump. The general mayoral election is slated for 4 November, making the race for leadership of one of the largest U.S. cities a compelling and closely watched political event.
