The triumph of a democratic socialist in the D.C. mayoral race is the latest sign that younger urban voters are turbo-charging candidates who promise to go big on affordability and take on President Trump. Why it matters: While Washington joined New York and Seattle as the latest big city to elect a democratic socialist, Janeese Lewis George's victory was less about her political label than about punishing prices and anger at the president. State of play: Lewis George, who handily defeated a moderate in the Democratic primary, marks a break from decades of business-friendly politicians running the nation's capital. Three trends explain her rise: Unhappiness with the city's direction stood at the highest level (55%) since Marion Barry's reign 28 years ago, per a Washington Post-Schar School poll. A lot of that disaffection was driven by Trump, but there was also a shout for change after three terms of Mayor Muriel Bowser.Washington's influx of white residents, who tend to be younger and more progressive, made winning that vote even more important, and Lewis George ran up the score in neighborhoods where they've settled. She also proved critics wrong by winning in majority-Black, working-class communities — the only place she lost was the city's wealthiest enclave, Northwest's Ward 3. Nearly half of D.C.'s registered Democrats have a favorable view of socialism, per the poll — so it's not a turnoff. Three other progressives led D.C. Council races, giving the presumptive mayor powerful allies. Zoom in: Lewis George appears to have broken through by: Echoing New York City Mayor Zohran Mamdani, she made the cost of living her No. 1 issue. Her rival, Kenyan McDuffie, ran on public safety and called her soft on crime, even as violence was fading as a top issue. Assembling a potent get-out-the-vote machine that encompassed almost every major local union plus the Democratic Socialists of America's local chapter, which helped knock on what she says were 200,000 doors.Crafting
