Zohran Mamdani’s presumed victory over Andrew Cuomo in New York City’s Democratic primary for mayor on Tuesday evening marks an extraordinary upset that until recently seemed all but unthinkable for the far-left state assemblyman from Queens who entered the race last October with virtually no name recognition. 

The stunning rise of the 33-year-old democratic socialist with a long history of anti-Israel activism sent shockwaves through New York City’s political establishment and is already reverberating beyond the Big Apple, raising questions over the ideological direction of the Democratic Party as it has struggled to land on a cohesive messaging strategy to counter President Donald Trump. 

With the midterms looming, Trump’s allies are already reportedly preparing to link Mamdani’s radical politics to the broader Democratic brand.

Meanwhile, in a place home to the largest Jewish population of any city in the world, Mamdani’s path to the nomination is also contributing to a growing sense of political homelessness among Jewish Democrats who voiced discomfort with his strident criticism of Israel and refusal to condemn extreme rhetoric such as “globalize the intifada,” a slogan that critics interpret as fueling antisemitism.

Cuomo, the scandal-scarred former governor of New York, leaned into his support for Israel and raised alarms about the rise of antisemitism as he courted Jewish voters. But his message ultimately failed to resonate over Mamdani’s sustained focus on affordability, including calls to “freeze the rent” that galvanized younger voters who turned out en masse.

While the final primary results are unlikely to be fully counted until next week because of the city’s ranked-choice system, Mamdani, with nearly 44% of first-place votes, held a commanding seven-point lead over Cuomo on Tuesday night — forcing the former governor to deliver a concession speech earlier than most had expected.

“Tonight was not our night,” Cuomo said at his election night watch party in Manhattan. “Tonight was Assemblyman Mamdani’s night.” He said he had called Mamdani to congratulate him for “a great campaign” that “touched young people and inspired them and moved them and got them to come out and vote.”

“He deserved it,” Cuomo concluded. “He won.”

Mamdani, for his part, said in his own speech that he would “be a mayor for every New Yorker,” and sought to assuage voter concerns about his views on Israel and the Middle East. “There are millions of New Yorkers who have strong feelings about what happens overseas. Yes, I am one of them,” he said, adding, “You have my word to reach further, to understand the perspectives of those with whom I disagree.”

Mamdani’s insurgent victory five months into President Donald Trump’s second term was reminiscent of then-upstart Rep. Alexandria Ocasio-Cortez’s upset primary victory over then-Rep. Joe Crowley in the spring of 2018, one of the seminal moments that year of the political backlash to Trump. It was an early signal that the party, even as it elected a number of moderate lawmakers in that year’s Democratic wave, was moving inexorably leftward in reaction to a Trump White House.

Even as Mamdani is poised to win the Democratic nomination, the two-term state legislator is facing a potentially messy general election that Cuomo could enter on a separate ballot line. The former governor indicated on Tuesday that he would “take a look” at the race and would “make some decisions” but gave no clear confirmation of his plans.

As Cuomo mulls his decision, it remains unclear who will emerge as a moderate standard-bearer in the November election, though the primary results were sure to be an encouraging turn for Eric Adams, the embattled mayor running as an independent — and whose team was hoping for a Mamdani victory.

The crowded general election also includes Jim Walden, a centrist independent, and Curtis Sliwa, the Republican nominee, raising the specter of a fractured vote that could help propel Mamdani to Gracie Mansion. 
Given that possibility, one Jewish leader in New York City recently speculated to Jewish Insider that Republicans would choose to unite behind Adams over Sliwa, “because then you have a real chance of winning.”
