Trump can no longer vote in the city that he called home for more than seven decades, but he got involved in the race anyway. He erroneously declared Mamdani a Communist and gave the younger Cuomo an eleventh-hour endorsement that the candidate, running as an independent, didn’t really want. But Trump will offer more than antagonistic rhetoric; he’s promising dramatic action, too. He warned in a social-media post last night that he would slash federal funding to the nation’s largest city because he had a “strong conviction that New York City will be a Total Economic and Social Disaster should Mamdani win.” And, his aides tell me, making good on that threat would be just the beginning.
