NYC mayoral rivals unite against billionaire ‘election interference’ as campaign enters final stretch

Republican Curtis Sliwa refuses to withdraw from the New York City mayoral race despite billionaire calls, creating an unlikely alliance with Democratic opponent Zohran Mamdani.

Several blocks downtown at his own press conference Monday morning, Mamdani admitted his surprise to agree with Sliwa. 

"I never thought I would say this, but here we are, where the only candidates who agree that billionaires shouldn’t control the future of this city are the Republican nominee and the Democratic nominee," Mamdani said. 

Catsimatidis, who is also the CEO of WABC Radio, publicly urged Sliwa to drop out of the race on Monday. Sliwa has long hosted a radio program on WABC but is on leave while he runs for mayor. 

"Curtis would make the best mayor of all the candidates … but Curtis has to realize that he should love New York more than anything else," he said. "It certainly looks like Curtis should pull out right now." 

"I’m not dropping out," Sliwa reaffirmed to reporters on Monday while responding to Catsimatidis’ plea.

Ackman and Catsimatidis are among those billionaires arguing that a vote for Sliwa is a vote for Mamdani. 

"Like that Ackman, out in Chappaqua, what does he know about New York City?" Sliwa questioned on Monday, telling reporters that billionaires "have paved the way for Zohran Mamdani because every time they fail, it makes it easier for Zohran Mamdani to campaign."

"They should stay out of it, focus on Wall Street, hedge funds. They know nothing about the streets, as clearly evidenced by their panic," Sliwa said, urging billionaires to "let the people decide." 

"Billionaires should be ashamed of themselves for interfering with this election. I call it election interference. Let the people decide. That’s the way I was raised. That’s the way everybody was raised. Nobody was ever told the billionaires were going to pick the person who wins an election."

Mamdani agreed with his Republican opponent on Monday, arguing that New Yorkers "no matter what they think about our politics, want to make their own decisions, and that is one place where Curtis and I agree, which is that it’s time for New Yorkers to make this decision, not for billionaire donors to decide who gets to run this city."

"To have a candidate spending all his time pleading with another candidate to get, it shows that he doesn’t have much to share with New Yorkers himself," Mamdani said of Cuomo. 

Fox News Digital reached out to Cuomo for comment but did not immediately receive a response.
