“Any Jewish person that votes for Zohran Mamdani, a proven and self-professed JEW HATER, is a stupid person!!!” Trump wrote on his social media platform, Truth Social.
Mamdani, 34, a progressive Democrat known for his outspoken left-wing positions, is running a campaign centered on affordability, housing reform, and expanding public services.
Polls suggest he is favored to win Tuesday’s election, which would make him the city’s first Muslim mayor.
Trump’s comments come in the final hours of the campaign, adding a sharp national political edge to a local contest already marked by debates over identity, religion, and representation.
Mamdani has not immediately responded to Trump’s statement.
Earlier, he endorsed former New York Governor Andrew Cuomo in his independent bid for New York City mayor, while urging voters to reject Mamdani, whom he labelled a “communist” and “a disaster for the city.”
