Her unapologetically expansive, left-wing agenda includes subsidized or even free childcare, increased down payment assistance for homebuyers and community resources to reduce crime, plus a promise to aggressively confront President Donald Trump’s attempts to reshape the nation’s capital.

“People are tired of hearing what government can’t do. They want to hear what government can do,” Lewis George said in an interview before the city’s primary, where she defeated her Democratic opponents and positioned herself to win the general election in November in a city dominated by Democrats.

Lewis George’s victory signals a break with a quarter-century of centrist governance in Washington, and it puts her in the vanguard of democratic socialists who have ascended in urban politics over the last year. Zohran Mamdani toppled Andrew Cuomo, the scion of a political dynasty, on his way to becoming New York City mayor. Katie Wilson won an upset victory to lead Seattle last fall. And this month, Nithya Raman clinched a spot in the November runoff against Los Angeles Mayor Karen Bass.

All of them are members of the Democratic Socialists of America, or DSA. The political organization has seen its membership ranks swell from a few thousand to more than 100,000 nationwide over the last decade after an influx of younger Americans joined following the presidential bids of Vermont Sen. Bernie Sanders, also a self-described democratic socialist.

There’s little sign of national coordination among the candidates, and it’s unclear whether voters are gravitating toward their promises of improved government services, their vows to fight the Trump administration or their critiques of capitalism.

But from coast to coast, confrontational progressives are advancing in mayoral races. City leaders can draw outsized attention for their successes and failures, and democratic socialists will be under pressure from residents to deliver on their vows for a new kind of governance. Whether that translates to national politics is a next test for their movement.

“They are all channeling a displeasure with a status quo and a serious desire for economic populism that the establishment Democratic Party hasn’t been preaching,” said Eric Stern, a Democratic strategist with Fight Agency, a political consulting firm that strategized Mamdani’s mayoral campaign.

Stern added that Democratic voters appeared more willing to support the most progressive candidate in mayoral races rather than in contests for the U.S. House. Candidates like Mamdani and Raman, Stern said, are “daring voters to dream and fall in love not just with the individual candidates but also the political process as a whole.”

A rising left navigates America’s urban challenges

The trend of progressives surging in urban areas may have limits for its broader impact on Democratic politics. Democratic mayors in cities including Atlanta, Houston, Miami and San Francisco won on relatively moderate platforms in recent years.

Progressive have also faced noteworthy challenges. Chicago Mayor Brandon Johnson was endorsed by the city’s DSA chapter during his 2023 mayoral run but has since faced criticism from both moderate and liberal local leaders on issues such as immigration, the local budget and public safety. Recalls and public pressure ousted progressives elected to district attorney offices in multiple jurisdictions over the last five years, when criminal justice reform efforts ran into dissatisfaction over public disorder following the COVID-19 pandemic.

Trump’s hardline immigration and law enforcement tactics have also become a challenge for liberal cities. The president’s agenda poses an especially serious threat to Washington, D.C., because of its status as a federal territory.

“Maybe we take back Washington and run it on a federal basis,” Trump told reporters this month when asked about the potential election of a democratic socialist as the district’s mayor. “We won’t put up with it.”

But progressives hope the current wave of anti-Trump furor in deep blue cities across the country will help buoy the chances of those on the hard left.

“It’s not folks looking for the leftmost option so much as looking for a candidate who’s gonna be on their side,” said Ravi Mangla, speaking for the left-wing Working Families Party. The party often endorses the same candidates as the DSA and is readying to target more mayoral offices in the country’s biggest metropolises this fall and in 2028.

“It’s less about whether you are on the right or on the left so much as whether you are willing to punch up at the powerful,” he added.

Mamdani and Lewis George are both self-described “sewer socialists” who emphasize the need for responsive government services rather than critiques of market economics. The phrase recalls the socialist Gilded Age mayors whom critics derided as too preoccupied with managing public works projects.

The term’s revival is partly a strategic move to align leftist ideas with concerns over affordability and the economy, voters’ top concern in the midterm elections, and shift the public perception of democratic socialists from firebrands who support radical policies to independent-minded public servants.

“This is absolutely a change election and I’m excited to bring the change that people want, which is really putting people first in the city and having the moral clarity and courage to stand up to Trump,” Lewis George said.

For voters the ‘socialist’ label did not seem to matter

While conservatives have used the “socialist” label to attack Democrats as extreme or incompetent, some D.C. voters appeared ambivalent before Tuesday’s primary.

Several lifelong residents said they believed Lewis George was a “fighter” but didn’t think she’d have much of an impact on the local economy, given the city’s status as a federal district.

“I go back and forth on my own labels and whether I am supportive of that movement or not, but I am supportive of making D.C. more affordable,” Owen Fitzgerald, a University of Maryland graduate student, said of his support for democratic socialism.

Fitzgerald voted for Lewis George because she would stand up to Trump and said he’d first learned of her campaign from friends in his neighborhood. But he didn’t know she was a democratic socialist until he saw news reports describing her with the label.

“It sends a cultural message to this administration that the people who are surrounding them in the capital are opposed to their platform, opposed to their political agenda, and I think that it will send a message, both nationally and internationally,” Fitzgerald said.
