Socialists Are Setting the Agenda in New York City

Two key primaries in New York City delivered whopping victories for an emboldened left led by Mayor Zohran Mamdani on Tuesday, as democratic socialists sought to define the future of the Democratic Party.

Mamdani-backed congressional candidates Claire Valdez and Brad Lander were declared the winners in their two districts less than half an hour after polls closed. While democratic socialist challenger Darializa Avila Chevalier was still neck-and-neck with fifth-term incumbent Rep. Adriano Espaillat, one message from the night was clear: The left isn’t just having a moment — it’s dictating how Democrats play the game of electoral politics.

“Even when we are outspent, our agenda and operation bring out voters in a way the Democratic Party establishment no longer aspires to,” Gustavo Gordillo, co-chair of the New York City chapter of the Democratic Socialists of America, told The Intercept. “It is democratic socialists who are defining much of the political terrain in New York.” 

Several races played out as proxy wars between the Democratic Party establishment and progressive insurgents, or even between progressives and socialists, to prove who would do more to disrupt the status quo. In hotly contested primaries spanning four out of five NY boroughs, candidates touted endorsements from Mamdani and Sen. Bernie Sanders, I-Vt., as well as their proximity to the most unconventional wings of the Democratic Party. 

As Pennsylvania Sen. John Fetterman put it to CNN on Tuesday, “The dirtbag left is surging.”

Rep. Dan Goldman, D-N.Y., fell to Lander less than 10 minutes after polls closed Tuesday night. Goldman, an heir to the Levi Strauss fortune and a staunch supporter of Israel, had lagged in the polls for months, suggesting the energy on the ground was firmly against the incumbent.

That momentum among progressives and the left has forced Democrats close to the party’s establishment to change the way they campaign. And the rise of the DSA chapter in New York following Mamdani’s upset win last year has also raised questions about how the progressive and socialist wings of the party will share power as they seek to expand their coalition beyond New York and across the country. Some critics condemned socialist darling Rep. Alexandria Ocasio-Cortez, who rose to power eight years ago with her own insurgent campaign against a powerful incumbent, for staying out of New York’s congressional primaries — while others theorized that the congresswoman and the mayor were dividing their political clout across competitive federal and state-level races. 

The primaries also created an unusual lane for the progressive New York Working Families Party, which found itself siding with the establishment it has long fought by backing Brooklyn Borough President Antonio Reynoso, outgoing Rep. Nydia Velázquez’s handpicked successor, against DSA candidate Valdez.  

Jasmine Gripper, co-state director for the New York Working Families Party, said the efforts to sow division with DSA or to separate WFP from the left’s rise erased its legacy — helping to defeat efforts to gut the party and fight conservative Democrats like former Gov. Andrew Cuomo; winning a $15 minimum wage; and expanding investments in pre-K and paid sick and family leave— and ignored that WFP was part of a much broader coalition that helped Mamdani beat Cuomo last year. 

“The Working Families Party has been at the forefront of literally every major victory that has actually tangibly helped working families, and so to call us establishment is to not know our history and to not know the history of New York,” Gripper said. 

She said WFP’s role moving forward was to work in tandem with DSA, not to compete with it. 

Lander, who represents the clearest bridge between socialists and progressives out of the three Mamdani-endorsed congressional candidates, was the first to sail to victory Tuesday night, when The Associated Press called the race in his favor just minutes after polls closed and with roughly a third of votes counted.

“There was a point where there was no one to the left of the [Working Families] party, and if you were to the left of the party, you were crazy,” she said. “Now we’re in a moment where there’s a whole entity that’s to the left of the WFP, and that is OK.”
