How Zohran Mamdani is reshaping Brooklyn’s Democratic map

For decades, Chuck Schumer and Hakeem Jeffries embodied Brooklyn’s political ascendancy. Schumer, 74, came from a middle-class Jewish family and rose through Harvard to the Senate’s top ranks. Jeffries, 55, represents a younger generation from Brooklyn’s Black middle class. Together, they built the borough into a powerhouse of Democratic leadership. Yet as Mamdani’s campaign gained traction, both appeared hesitant—Schumer staying silent, Jeffries reluctant until the pressure became untenable. Their delay only deepened the perception that Washington Democrats were out of touch with their own neighbourhoods.

A proxy war for the party’s soul

In districts like Brooklyn’s 35th—where a once-Black majority has become a white plurality—the political spectrum now runs from “super left” to “just left.” Councilmember Crystal Hudson describes local politics as a “proxy war” between Mamdani’s DSA allies and the old Democratic machine. Former Governor Andrew Cuomo, campaigning for the centrist side, framed it bluntly: “It’s not just about people or parties—it’s about philosophies.” To him, Mamdani represents an ideological challenge that could tarnish Democrats’ brand nationally, even as it energizes younger voters.

The cultural clash

The divide isn’t only ideological; it’s generational and cultural. Longtime Brooklynites remember Schumer’s synagogue speeches and local fundraisers. Now, Mamdani rallies spill into Instagram stories and TikTok clips. Young creatives and transplants see his campaign as part of a wider shift in how attention and activism intersect. “They understand the culture of attention,” said one supporter in Cobble Hill, echoing a sentiment that traditional politicians struggle to command the energy of the digital left.

Schumer’s synagogue dilemma

Even within Schumer’s spiritual home, Congregation Beth Elohim, divisions are sharp. Rabbi Rachel Timoner, long a critic of Israel’s right-wing government, hosted Mamdani for a recent town hall. The candidate’s refusal to disavow controversial pro-Palestinian slogans unsettled many congregants, still grieving the violence that followed October 7, 2023. Yet hundreds attended, eager to listen. “Some said, ‘There’s no chance I’m voting for him, but I’m glad we did this,’” Timoner recalled. For a borough shaped by activism, dialogue itself has become an act of political courage.

The old clubhouse fights back

Across town, the Thomas Jefferson Democratic Club—the last stronghold of Brooklyn’s machine politics—rallied behind Andrew Cuomo over pastrami sandwiches and folding chairs. Club chairman Frank Seddio, 79, dismissed the Mamdani movement as performance politics. When Cuomo denounced Mamdani’s proposed rent freeze as “a gift to gentrifiers,” the crowd roared in approval. “This,” Seddio said proudly, “is the real politics.” But even here, the unease was palpable—an acknowledgment that the world outside the deli no longer plays by old rules.

What Brooklyn tells us about Democrats nationwide

Brooklyn’s fight mirrors the national Democratic tension between pragmatism and purity, between incumbents managing institutions and insurgents demanding reinvention. It’s about housing and identity, Gaza and gentrification, old power and new energy. The borough that once united the party’s most influential leaders now reveals its deepest divide. As one former council member put it, “Now I know how my parents felt when George McGovern replaced Hubert Humphrey.”

In Brooklyn’s narrow streets and crowded town halls, the Democratic Party’s future is being written—not by consensus, but by contest.
