On Sunday night in Queens, the vibrations from thousands of cheering Zohran Mamdani supporters reverberated throughout Forest Hills Stadium, as the audience burst into the same chant as speaker after speaker took the stage: “DSA, DSA.”
Mamdani’s surge past former Gov. Andrew Cuomo in June’s Democratic primary for New York City mayor didn’t just put the 34-year-old state assemblyman on the political map. It also highlighted the Democratic Socialists of America, or DSA — a spotlight that’s growing brighter as Mamdani enters next week’s general election as the frontrunner.
The organization known for attacking a capitalist-oriented status quo in the name of fighting for working-class people has grown in prominence in recent years in part due to its association with figures like Sen. Bernie Sanders, I-Vt., and Rep. Alexandria Ocasio-Cortez, D-N.Y. And its contours continue to evolve, as Mamdani — who identifies himself as both a Democrat and a democratic socialist — prepares for what could be the organization’s most important electoral result yet.
“I call myself a democratic socialist, in many ways inspired by the words of Dr. King from decades ago. ‘Call it democracy, or call it democratic socialism, there has to be a better distribution of wealth for all of God’s children in this country,’” Mamdani said on NBC News’ “Meet the Press” this summer.
But socialism is also unpopular throughout much of the country, used as a cudgel against Sanders in his presidential campaigns and against Democratic candidates more broadly, too.
“This is a Democratic city with a Democratic tradition, and Zohran is not a Democrat,” Cuomo charged recently. “Democratic socialist is a different thing.”

NBC News spoke with Mamdani supporters and a member of the DSA’s national political committee, Kareem Elrefai, on how they see the mission and evolution of the group as it reaches new prominence. (Mamdani has been endorsed by DSA’s New York chapter but not the national organization.)
Elrefai points out that DSA is not a party, but “operates kind of like a party.”
“I would say that we are an organization of organizers,” Elrefai said. “I think being an organizer charges you with something more than just being an activist. An organizer is somebody that recognizes that it’s solidarity and working-class power that is going to take us to where we need to be, where we have an economy that works by and for the working class — not for billionaires.”
Mamdani is running to lead a city of 8 million people with a budget of $100 billion and 300,000 city employees. His centerpiece policy proposals — free buses, some city-owned grocery stores, a rent freeze on roughly a million rent-stabilized units and universal child care — channel the economic populism that DSA has embraced. He’s proposed raising taxes on millionaires by 2% and increasing New York City’s corporate tax rate to match New Jersey’s to pay for some of those programs.
Universal child care, for example, has an estimated cost of $6 billion.
“We think that the best way to make New York a successful city is to end the policies that have turned it into a playground for the rich,” said Gustavo Gordillo, a New York City DSA member.
When asked about concerns that higher taxes might cause wealthy New Yorkers to flee, Gordillo said: “You can’t get what New York offers anywhere else in the country. We know that we’ve raised taxes on the rich in the past … and they haven’t left.”
