Nithya Raman defeated incumbent Karen Bass to become Los Angeles mayor, making America's two largest cities — LA and New York — both led by democratic socialist mayors. Raman, the first DSA member on LA's city council when she won in 2020, entered the mayoral race late, propelled by public fury over Bass's handling of the January 2025 Palisades fire. The result was less ideological conversion than voter punishment: a significant majority of Angelenos believed the city was on the wrong track, and Bass wore the blame. The DSA-LA slate went far beyond the mayoral race. Marissa Roy won the city attorney seat with 67.39% of the vote, pledging to turn the office into "the largest public interest law office in the city." Angela Gonzales-Torres defeated nine-year incumbent Jimmy Gomez for a US House seat with 60.6% of the vote. Gomez had been backed by AIPAC, which spent $2.7m supporting his candidacy. Other DSA-endorsed candidates won school board seats and enough Burbank city council seats to create what the chapter calls the first socialist-majority city council on the west coast. The organizational infrastructure behind these wins is concrete: 110,000 doors knocked, 6,000 members as of last month, with another 2,000 joining in the week after the election. DSA-LA's power has been accumulating since Raman's 2020 council win — an upset that toppled a Democrat backed by Pelosi and Clinton. Three more DSA candidates have since joined the 14-member council. Zev Yaroslavsky of UCLA's Luskin School called the pattern "pretty sophisticated" in resource targeting, noting the organization's strength is human capital, not donor money. The Raman endorsement was not clean. She entered late, after DSA-affiliated council colleagues had already backed Bass. The chapter censured Raman in 2024 for pursuing an endorsement from a Democrats for Israel group. The national DSA considered rescinding the chapter's endorsement over her position on the BDS movement; the vote to rescind narrowly failed. Her own DSA-affiliated council allies stood by Bass. This is not a story of seamless party discipline — it is a coalition managing real internal contradictions. The deeper question is structural. DSA-LA's platform — affordable housing, tenant rights, immigrant rights, Medicare for All, Green New Deal — polls well in a city where cost of living has outrun wages for two decades. But polling well and governing well are different problems. Raman inherits a city with deep infrastructure deficits, a homelessness crisis, and fire-ravaged neighborhoods demanding immediate action. The progressive critique of incumbents is easier to sustain from opposition than from the mayor's office. The Palisades fire was the accelerant, not the fuel. Bass's approval had been declining before the fire, but the disaster crystallized a broader legitimacy crisis: residents felt city government could not deliver basic services. Raman's victory speech acknowledged the gap directly — pledging to "earn your trust in this city again" among voters who backed Bass or didn't vote at all. The implicit admission: winning an election is not the same as having a mandate. What makes this worth watching is the scale of the test. A DSA mayor, city attorney, council bloc, congressional representative, and school board members — all in the nation's second-largest city. If this cohort can deliver measurable improvements in housing, fire preparedness, and transit, it becomes a replicable model. If it fragments under governing pressures or gets boxed in by Sacramento and federal constraints, the 2020-2026 wave becomes a cautionary tale about the distance between organizing and administration.
