Nassau County Executive Bruce Blakeman stood before roughly 150 people in a Queens park Sunday morning and delivered a blunt verdict on New York City Mayor Zohran Mamdani: the mayor has a "dark heart," is "un-American," and is stoking division in a city that deserves better.
The rally at Yellowstone Park in Forest Hills was organized to protest what a press release for the event called a "staggering" hate crime spree across the borough. Blakeman, now a GOP candidate for governor, headlined the gathering and used it to sharpen a line of attack that has been building for months, that Mamdani's earliest moves in office signaled where his sympathies lie.
The target was specific. Blakeman zeroed in on a decision Mamdani made almost immediately after taking power: altering the city's working definition of antisemitism. As the New York Post reported, Blakeman told the crowd and the paper directly:
"One of his first acts as mayor was to change the definition of antisemitism. We don't have enough problems in the city? That was the first thing he had to do?"
That question, why a new mayor would prioritize redefining antisemitism over the city's long list of urgent problems, is the kind of thing that sticks. It frames the issue not as an abstract policy dispute but as a window into what the mayor actually cares about.
Blakeman did not hedge. Speaking to the Post, he laid out his case in plain language:
"He's got a dark heart. He's un-American and he's antisemitic. And he's got to change or otherwise this city will rise up against him because this is a city of good people."
He went further, drawing a contrast between the city's character and its mayor's conduct:
"This is a city of every race, religion, ethnic group. People of all abilities and lifestyles. And they should all be living together in peace and harmony. And not have a mayor that divides us."
Those are fighting words from a county executive positioning himself for a statewide run. But they also reflect a frustration that extends well beyond partisan politics. Jewish New Yorkers watching hate crimes climb in their neighborhoods don't need a gubernatorial candidate to tell them something is wrong. They can see it.
The rally came on the heels of a protest outside Park East Synagogue the previous week, another sign that tensions in the city are not cooling down but intensifying. Mamdani's critics say his administration has been slow to take those tensions seriously, and that his early policy choices made things worse.
Blakeman was not the only speaker to go after Mamdani. Comedian Zach Sage-Fox took the stage and broadened the attack to include the mayor's wife, Rama Duwaji, whose social media history has become a recurring liability for the administration.
In March, a flurry of alarming social media activity involving Duwaji resurfaced. The Post previously reported that the activity included liking Instagram posts that celebrated Hamas's October 7, 2023 terror attack against Israel. The resurfacing of those posts put the mayor's office in an uncomfortable spotlight, and Sage-Fox made clear he had no interest in letting the moment pass.
He told the crowd that Mamdani was "playing both sides of the coin" and refused to take responsibility for rising antisemitism that, in Sage-Fox's view, the mayor helped create over the course of his political career:
"We have a person running this city who takes no accountability for the rise of antisemitism that he helped create over his political career. I'm sorry, but it's the truth, he's playing both sides of the coin."
Sage-Fox then turned to Duwaji. His argument was blunt: at least the mayor's wife is consistent. It's Mamdani's two-faced posturing that draws the real contempt.
"I'd rather him be honest. At least his wife doesn't play both sides. At least she says who she is. Her silence is complicity and at least we know what we're dealing with."
He added: "But no, the two-faced stuff, it's BS and we're not going to stand for it. We're not going to stand for it."
Mamdani did not respond to the rally's charges in the Post's account. That silence fits a broader pattern. The mayor has repeatedly declined to answer politically uncomfortable questions, choosing careful positioning over direct engagement.
His critics see the same instinct at work on antisemitism: public statements designed to sound balanced while his earliest official actions, and his wife's social media trail, point in a different direction.
The gap between Mamdani's rhetoric and his record has been a recurring theme. He entered office with sweeping promises, but the follow-through has been uneven. His retreat from a signature free-bus pledge drew criticism from supporters who expected him to deliver, not dilute.
And the backlash hasn't come only from the right. Residents in his own political base have pushed back on administration decisions, including a lawsuit to block a homeless shelter in the East Village, a fight that showed even Mamdani's own voters are willing to challenge him when his policies land in their neighborhoods.
A gathering of 150 people in a Queens park is not, by itself, a political earthquake. But the Sunday rally matters for what it signals about the landscape Mamdani now faces.
Blakeman is running for governor. He has every reason to draw a sharp contrast with the city's Democratic mayor. But the people who showed up at Yellowstone Park weren't there for a campaign event. They were there because hate crimes in their borough have reached a level the organizers called "staggering," and they feel their mayor is part of the problem.
That is a dangerous position for any elected official, especially one who has worked to cultivate a public image as a unifier. Questions about Mamdani's broader ambitions only sharpen the scrutiny. If you can't hold your own city together, what exactly are you building toward?
Several open questions remain. What formal action did Mamdani take to change the city's definition of antisemitism, and what did the change actually say? What has his administration done, concretely, in response to the rising hate crime numbers in Queens? And does the mayor intend to address the social media revelations involving his wife, or will the silence continue?
None of those questions were answered Sunday. The crowd in Forest Hills noticed.
When 150 New Yorkers give up a Sunday morning to stand in a park and demand their mayor take antisemitism seriously, the problem isn't the people in the park.
