Mamdani’s stunning upset in New York’s Democratic mayoral

primary carries risks, rewards for national Democrats

Self-described democratic socialist Zohran Mamdani’s unexpected upset in New York City’s Democratic mayoral primary on Tuesday exhilarated progressive activists, who had banded together to prevent the more moderate former New York Governor Andrew Cuomo from triumphing.

But the surprise outcome also generated excitement from a very different group of people: national Republicans.

Soon after it became clear that Mamdani, a 33-year-old state lawmaker, was likely to prevail, Republican Vice President JD Vance sent congratulations on social media to the “new leader of the Democratic Party.” The Republican’s congressional campaign arm called him an “antisemitic socialist radical” and promised to tie him to every vulnerable Democrat in next year’s midterm elections.

And on Wednesday, Republican President Donald Trump – a native New Yorker – piled on, writing on social media, “It’s finally happened, the Democrats have crossed the line. Zohran Mamdani, a 100% Communist Lunatic, has just won the Dem Primary, and is on his way to becoming Mayor.”

The reactions underscore both the risks and the rewards for the Democratic Party – still trying to find its footing five months into Trump’s term – in having an unabashed left-wing nominee running in the country’s biggest city this fall.

Mamdani’s campaign, which drew plaudits for its cheery tone and clever viral videos, could help energize young voters, a demographic that Democrats are desperate to reach in 2026 and beyond. His rise from a virtual unknown was fueled by a relentless focus on affordability, an issue Democrats struggled to address during last year’s presidential race.

“Cost of living is the issue of our time,” Neera Tanden, the chief executive of Democratic think tank Center for American Progress wrote on X in response to Mamdani’s win. “It’s the through line animating all politics. Smart political leaders respond to it.”

His history-making candidacy – Mamdani, born in Uganda to Indian parents, would be the city’s first Muslim and Indian American mayor – could also drive engagement among Asian and especially Muslim voters, some of whom soured on the party after the Biden administration’s support for Israel’s war in Gaza.
