Two years ago, Darializa Avila Chevalier, a 32-year-old sociology graduate student at the City University of New York, was sitting in a tent on Columbia University’s quad as part of the pro-Palestine encampment on its campus. This month, Chevalier, the daughter of a truck driver and a case worker from the Dominican Republic, soundly defeated five-term incumbent Rep. Adriano Espaillat to become the presumptive next member of Congress for New York’s 13th congressional district, where Columbia sits.

“I kept thinking of all of the folks who have really been let down by a lot of establishment Democrats. I was thinking of my friend Mahmoud [Khalil],” Chevalier said in an interview: the Palestinian campus organizer and recent Columbia masters graduate who became the face of a new, more punitive phase of Donald Trump’s policy of political detainment and deportation when DHS agents kidnapped him from his apartment building last year.

When Khalil was taken, Espaillat sent out a two-sentence statement urging due process: too little, too late, Chevalier said. Khalil was released the same week Zohran Mamdani won New York’s Democratic mayoral primary. A year later, with Mamdani’s backing, Chevalier won her own race alongside a slate of New York candidates who championed the Palestinian cause throughout their campaigns—often in ways that, until very recently, constituted a political third rail.

Those relative outsiders—many backed or recruited by groups like Justice Democrats and the Democratic Socialists of America, new kingmakers like Mamdani, and influencers like Hasan Piker—are notching upset victories against incumbents with decades of experience.

It echoes the wave that brought challengers like New York Rep. Alexandria Ocasio-Cortez or Minnesota Rep. Ilhan Omar to office—and eventually made them icons of the Democrats’ left flank. But those races, close to a decade ago, didn’t feature Israel-Palestine politics in anything like the same way, a door opened in part by Zohran Mamdani’s........
