All three congressional candidates that New York City Mayor Zohran Mamadani endorsed won their primaries on Tuesday. The races were widely viewed as a test of just how much influence the left would have in charting the next chapter for the Democratic Party — and a referendum on Mamdani's power.

“Mamdani is the one variable that truly matters,” Michael Lange, political writer and elections analyst of The Narrative Wars Substack, tells The Intercept Briefing as he breaks down the wins of Claire Valdez, Brad Lander, and Darializa Avila Chevalier by district. “You pair that type of broad cultural political figure with the block-by-block organizing of New York City DSA — it's a very powerful thing.”

“You had a candidate who said ‘Fuck Kamala Harris’ win the historic capital of Black America," says Lange, of Avila Chevalier’s win over five-term incumbent Rep. Adriano Espaillat. “If that is not a distillation of the ‘Democratic tea party,’ I don't quite know what is.”

This week on the podcast, host Akela Lacy speaks to Lange and Intercept managing editor Maia Hibbett about the strategic mistakes of the traditionally progressive Working Families Party, the growing influence of the Democratic Socialists of America on the Democratic Party, and how the DSA is upending electoral politics from the left.

“Here in New York, a lot of the momentum is being driven by the DSA, of course, but there are these progressive and insurgent candidates across the country who are trying to change the course of the Democratic Party," says Hibbett, “and excite voters who might not have been into the Democratic establishment in past cycles.”

Lange notes how demographic changes and pressures on the Democratic Party base are impacting voters’ priorities. “The party's becoming younger, more educated, and increasingly squeezed financially,” says Lange. “There's just this broad alienation of people who have not really been able to get ahead, not for their own fault, and I think it's like downstream of our economy, and that's why the affordability zeitgeist is so potent.” He adds, "You spin the wheels up in two years, what could this look like in a Democratic presidential primary?"
