NEWYou can now listen to Fox News articles! Billionaire John Castimatidis, WABC Radio and Red Apple Media CEO, publicly urged Republican New York City mayoral candidate Curtis Sliwa to drop out of the race on Monday. Catsimatidis, a Republican who launched his own mayoral campaign in 2013, cited concerns "that Sliwa’s continued candidacy could split the vote and inadvertently help another candidate." "Catsimatidis said the move is essential to consolidating support behind a ‘viable alternative’ and avoiding what he described as a potentially damaging outcome for the city if the vote remains divided," the release said. Sliwa was quick to respond, and he does not intend on going anywhere. "The billionaires can conspire to pick their candidate … I trust the people. They will make the decision. I will not drop out," Sliwa told Fox News Digital.

Zohran Mamdani, the Democratic nominee, appeared amused by the situation. "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," the democratic socialist Mamdani said.

"We know 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."
