There's a new boss in New York politics, and her name is Zohran Mamdani. Just over a year after the Democratic Socialist of America-backed mayor stunned the city, her machine proved it wasn't a fluke. Three candidates she endorsed won their House primary races Tuesday night. Two incumbents — neither backed by Mamdani — got the boot.
Let's not mince words: the Working Families Party and DSA alliance has become the most disciplined political operation in the state. They don't just win; they eat their own. The message is clear: get on board, or get out of the way.
The Winners' Circle
In Queens, former City Councilmember Tiffany Cabán—another DSA darling—locked down the nomination for the open 7th District seat. She beat a moderate Democrat by 18 points. Across the East River, Assemblymember Phara Souffrant Forrest crushed a two-decade incumbent in Brooklyn's 9th District. And in the Bronx, community organizer Samy Nemir Olivares took the 15th with a 22-point margin.
These aren't just wins. They're landslides. And they're all people who've sworn allegiance to Mamdani's brand of soak-the-rich, expand-Medicaid, defund-the-police activism.
"We ran on housing, healthcare, and telling the real estate lobby to go jump in the Hudson. And we won." — Tiffany Cabán, victory speech
Incumbents Get the Guillotine
The most brutal story of the night? Reps. Sean Maloney and Carolyn Maloney. No relation, but both got the same treatment: fired. Maloney—the DCCC chair, no less—lost to a 28-year-old activist who ran on a platform of "no more corporate PAC checks." Carolyn Maloney, a 27-year veteran, fell to a little-known state senator who promised to "bring the fire" to Washington.
This is not your father's Democratic primary. Seniority? Irrelevant. Fundraising? Overrated. If you're not with the movement, you're the target.
What Mamdani's Machine Means
Let's be real: Zohran Mamdani didn't run for any of these seats. But her shadow loomed over every ballot box. She campaigned for these three, cut robocalls, sent text blasts from her political action committee. Her endorsement is now the closest thing to a party stamp in New York City politics.
The DSA's strategy is simple: recruit true believers, primary anyone who wavers, and never apologize. It's working. Since Mamdani's mayoral win, the organization has tripled its membership in the state. They've got money, volunteers, and a brand that young progressives trust more than the Democratic Party itself.
The Other Side of the Coin
Not everyone's celebrating. Moderate Democrats are terrified. One party strategist told me, off the record, "They're going to nominate a socialist in a swing district and hand the seat to a Republican. Then they'll blame us for not being progressive enough."
That fear isn't baseless. The 7th District, where Cabán won, is a Democratic stronghold. But the 9th? It's purple. And the 15th? It's blue, but with a growing conservative Dominican population that didn't vote for this. National Republicans are already circling, planning to paint every DSA-backed candidate as "defund the police" radicals.
So What Happens Now?
Come November, these three will be under a microscope. If they win, the DSA solidifies its control of the state's congressional delegation. If they lose, the moderate wing gets ammo to push back. Either way, the party is fractured.
But here's the thing nobody wants to say out loud: the DSA doesn't care about losing general elections. They care about changing the conversation. And they've already done that. Every Democrat in New York now has to answer for their position on rent control, single-payer, and police funding. That's a win for the socialists, even if they lose a seat or two.
Mamdani's machine isn't just winning primaries. It's rewriting the rules of the game. Buckle up.
