Mamdani, Cuomo, Sliwa face off in NYC mayoral debate

NEW YORK (WABC) -- New York City mayoral candidates Andrew Cuomo and Curtis Sliwa tried to blunt Democratic front-runner Zohran Mamdani's momentum during a contentious first general election debate Thursday.

Cuomo, now running as an independent, spent much of the evening repeating his case that Mamdani lacks the experience to lead America's biggest city and that his agenda is too radically left. Mamdani, a self-described democratic socialist, hit back, criticizing the former governor's response to the COVID-19 pandemic and repeatedly raising sexual harassment allegations that Cuomo denies.

But it was unclear whether any candidate did enough to move the needle during their two hours on stage.

Mamdani on defense

Mamdani came under attack straight out the gate, as Cuomo highlighted his relative lack of job experience.

Cuomo, stressing his own executive experience, said being mayor "is no job for on-the-job training"

"This is not a job for a first timer," he said.

Mamdani hit back, criticizing Cuomo's integrity and decision-making as the COVID-19 pandemic spread through nursing homes.

"What I don't have in experience, I make up for in integrity. What you don't have in integrity, you can never make up for in experience," he charged.

Mamdani's brand of economic populism - a laser focus on lowering the city's astronomical cost of living through the idea that government should do more to help the lower and middle classes instead of wealthy people - has generated buzz and excitement.

At the same time, the state assemblyman's calls to raise taxes on wealthy people and intense criticisms of the Israeli government's military actions in Gaza have unnerved some centrists and conservatives. That's where Cuomo's rebooted campaign sees its path to victory.

The former governor has painted Mamdani as a potentially dangerous leader who would lead the city into financial and social ruin, while casting himself as a competent manager who can handle its expansive bureaucracy and finances.

Candidates create hypothetical headline of first year in office

Moderators at Thursday night's debate asked the candidates to create one headline describing their accomplishments after a hypothetical first year in office.

Andrew Cuomo's was less of a headline, and more of a listed of accomplishments, including lower rent, lower crime, education scores up, more jobs and optimism high.

Curtis Sliwa's headline was "Curtis Sliwa exceeds all expectations."

Zohran Mamdani's headline was "Mamdani continues to take on Trump, delivers affordability agenda for New Yorkers."
