When reached for comment, Republican nominee Curtis Sliwa told Fox News Digital, "De Blasio nearly destroyed NYC and defunded law enforcement. His endorsement of Mamdani is a warning. Mamdani is de Blasio 2.0, but far more dangerous."

Despite Mamdani's success reaching New Yorkers this year, the former mayor acknowledged that many are still skeptical that he can deliver on his ambitious campaign promises, writing, "I can say definitely — and I know better than anyone — that the answer is yes."
The former New York City leader said he faced the same criticisms during his tenure as mayor of the nation's biggest city, from 2014 to 2021.
"Throughout my time in City Hall, the argument that my vision was recklessly idealistic — that it was both unrealistic and fraught with dangerous unintended consequences — was thrown at my plans for affordable housing, paid sick days, the $15 minimum wage and most of all, pre-K for all — all initiatives I delivered on," he said.

The former mayor had refused to throw his political weight behind any of the mayoral candidates before Tuesday's announcement.
Signaling support for Mamdani and defending his campaign promises, de Blasio made it clear throughout the race that he would not endorse former Gov. Andrew Cuomo, trolling him on social media and fanning the flames of their long-held feud.
While de Blasio's endorsement shouldn't come as much of a surprise, several New York Democratic leaders continue to withhold their endorsements for Mamdani, despite his securing the Democratic nomination earlier this summer.

New York Gov. Kathy Hochul, House Minority Leader Rep. Hakeem Jeffries and Senate Minority Leader Sen. Chuck Schumer have yet to endorse Mamdani.
Fox News Digital reached out to incumbent Mayor Eric Adams, Cuomo and Mamdani but did not immediately receive a response.
