More than a thousand people packed the performing arts center at Lehman College in the Bronx on Sunday to hear Sen. Bernie Sanders (I-VT) demand higher taxes on the wealthy. The one prominent New York progressive who didn't bother showing up: Mayor Zohran Mamdani, the man whose entire governing agenda depends on exactly the policy Sanders was pitching.
Mamdani declined to join the rally or appear onstage, even as Sanders spent nearly an hour promoting a proposed extra 5% tax nationwide on anyone worth $1 billion or more and urging Gov. Kathy Hochul to back Mamdani's own 2% tax on New Yorkers earning $1 million or more. The mayor's absence speaks volumes about the fault lines running through New York's progressive coalition as budget deadlines in June and November elections loom.
The 84-year-old Vermont senator flew to the Bronx to make the case that New York City's mayor apparently couldn't make in person. Sanders deployed his familiar populist arithmetic, telling the crowd according to the New York Post:
"A few years ago, it was estimated that Elon Musk, the wealthiest man alive, paid an effective tax rate of less than 3.3%, while the average truck driver in America paid an effective tax rate of 8.4%."
He then pivoted to a direct endorsement of Mamdani's agenda, telling the audience:
"That is what the mayor of New York City is fighting for."
Fighting for it, just not in the room where it was happening.
Sanders also aimed squarely at Hochul, saying he would "ask Gov. Hochul to listen to where the people are at" and that he hoped she would "join the vast majority of the people who want to see that happen." It was less a policy argument than a pressure campaign, designed to box the governor into a corner with the weight of a packed auditorium behind it.
Mamdani's no-show is the latest signal that the relationship between New York City's new mayor and the state's Democratic governor is something less than functional. Since taking office in January, Mamdani has been pressuring Hochul to approve his proposed millionaire tax. Hochul has come out and said she would not support the legislation.
The past two months have featured alternating periods of tension and détente between the two. In February, Hochul funneled more than a billion dollars to New York City to help offset its budget deficit. Days later, Mamdani responded by threatening to hike property taxes in the city by nearly 10% if Hochul wouldn't sign his tax on the wealthy.
That sequence tells you everything about the dynamic. Hochul extends an olive branch worth ten figures. Mamdani pockets it and immediately threatens homeowners and landlords across the five boroughs. This is not a negotiation. It's a hostage situation where the hostages are New York City property owners.
And yet Mamdani has endorsed Hochul's bid for re-election in the fall. Some have speculated she is simply waiting to secure her seat before signing the controversial tax into law. If true, it would mean the governor's public opposition is theater, which is exactly the kind of governance New Yorkers have come to expect.
The rally's supporting cast was revealing. Grace Mausser, co-chair of the city's Democratic Socialists of America chapter, framed Hochul's resistance as a betrayal of voters:
"She is a public servant, and she owes us the decency of listening to us."
Her co-chair, Gustavo Gordillo, was more candid about the strategy at work. He described an "inside-outside strategy" with elected officials and insisted the DSA doesn't "take orders from the mayor." Then he laid out the goal plainly:
"We're here to build an agitational movement that's going to force the governor to tax the rich, and that's what the mayor wants as well."
Note the word: "force." Not persuade. Not convinced by the evidence that the policy will produce better outcomes. Force. This is the progressive movement in its honest form. When voters don't deliver the result, when governors resist, you build pressure until compliance is achieved. The democratic process is a tool when it works and an obstacle when it doesn't.
Gordillo also framed the situation as a binary choice, saying they want to tell Hochul "she needs to choose a side, whether she's on the side of the working class in New York or on the side of the billionaires and the 1%." This is the rhetorical trick that never gets old on the left: reduce every policy question to a moral binary so that anyone who disagrees is not merely wrong but evil.
Lost in all the rally speeches and populist applause lines is a basic question nobody on that stage bothered to answer: What happens when the rich leave?
New York already has among the highest state and local tax burdens in the country. The wealthy residents that progressives want to squeeze harder are also the most mobile. They have accountants, second homes, and the resources to relocate to states that don't treat success as a funding source for an ever-expanding government. Every new millionaire tax proposal assumes the target population will sit still and take it. History suggests otherwise.
Mamdani's approach is particularly striking in its contradictions. He wants Hochul to approve a 2% surtax on incomes above $1 million. When she declines, he threatens a nearly 10% property tax hike that would hammer middle-class homeowners, small landlords, and renters whose costs inevitably rise with property taxes. The people Sanders claims to champion, the truck drivers and working families, are the ones who would feel that property tax increase most acutely.
This is the progressive fiscal model in miniature:
It's a closed loop where government spending is never the variable and someone else's money is always the answer.
Bronx resident Rowshon Sharker, 52, spoke at the rally and addressed Hochul directly, saying voters put her in office and expect results. She also offered a telling line about the absent mayor:
"Mamdani trying to do his job, but we are the part of the people. We are here to say the words. We elected Mamdani for our basic needs, right, universal child care, housing and every point."
Universal child care. Housing. "Every point." The wish list is infinite. The funding mechanism is a 2% tax on millionaires that the governor won't sign. The backup plan is a property tax hike that punishes the very people filling those auditorium seats.
Mamdani skipped the rally because showing up would have meant standing next to Bernie Sanders while his own legislative agenda goes nowhere. It would have meant facing a crowd of a thousand people and explaining why, months into his tenure, the centerpiece of his platform remains stuck. It's easier to let Sanders do the talking and the DSA do the agitating while the mayor works the back channels.
A thousand people showed up to demand that Albany tax the rich. The mayor they elected to deliver it didn't even walk through the door.
