Democratic socialists are gaining traction in major U.S. cities, signaling a potential shift in the urban political landscape ahead of upcoming elections. Recent victories by candidates who openly embrace democratic socialism suggest an expanded role for left-wing politics within urban governance, despite persistent challenges in translating ambitious agendas into policy.

Zohran Mamdani, 34, who defeated former New York Governor Andrew Cuomo twice in his campaign to become New York City mayor, exemplifies this emerging cohort. His inauguration speech emphasized a move away from individualism toward collective action. Since taking office in the nation’s largest city, Mamdani has tempered some of his more radical commitments, aligning with practical governance needs. He retained Jessica Tisch, known for her moderate positions, as police commissioner and scaled back on promises to relinquish control of the school system and substantially expand costly housing subsidies. Mamdani has also cultivated working relationships with Governor Kathy Hochul, a centrist Democrat, and unexpectedly cordial interactions with former President Donald Trump, whom he once harshly criticized.

New York’s socialist mayor is part of a broader trend that includes Seattle, where a self-identified socialist currently serves as mayor, and Washington, D.C., where Janeese Lewis George recently won her Democratic primary with a platform emphasizing progressive policies. Lewis George, 38, campaigned on expanding child care assistance, constructing tens of thousands of new homes, and broadening rent stabilization measures. Her agenda addresses mounting concerns over housing affordability and child-rearing costs. Critics have dismissed her proposals as overly ambitious, but these messages resonated strongly with voters disillusioned by the perceived limitations of traditional Democratic leadership.

Some of these politicians are formal members of the Democratic Socialists of America (D.S.A.), while others are aligned with similar ideals without official affiliation. Across the board, they advocate for assertive government intervention in areas like housing and social services, distancing themselves from market-based solutions favored by more moderate Democrats. Their approach often involves direct engagement with business interests, including utilities, landlords, and large financial backers.

Despite some high-profile losses for left-leaning candidates in cities like San Francisco and Philadelphia, the momentum behind democratic socialism continues. Yet, governing remains a critical test. Fiscal constraints at the municipal level, combined with federal oversight—especially in Washington, D.C.—complicate efforts to implement expansive social programs.

Mary Cheh, a former D.C. council member, noted that while change is inevitable with the incoming representatives, expectations should remain measured given budgetary limitations. “Governing is a practical affair,” she said, acknowledging the appeal of Lewis George’s platform but cautioning against overestimating immediate transformation.

In Los Angeles, City Council member Nithya Raman, a democratic socialist elected amid the 2020 Black Lives Matter protests, is now challenging incumbent Mayor Karen Bass in a runoff election. Raman’s early association with progressive activism has given way at times to more moderate positions on development and housing policies, illustrating the compromises often required in urban governance.

Similarly, Seattle’s Mayor Katie Wilson, who identifies as a socialist but is not D.S.A.-affiliated, has prioritized housing initiatives but has also demonstrated a willingness to negotiate with more moderate council members. She conceded to implementing security measures during the World Cup despite initial opposition, underscoring the pragmatic decisions often necessary in office. Wilson has set ambitious housing targets but acknowledges the difficulties in making rapid progress.

While fiscal realities and political compromise shape much of their work, democratic socialists in these cities have tapped into widespread voter frustration with the status quo. Their capacity to deliver tangible improvements, even on smaller issues, is seen as foundational to building trust for broader reforms. As Lewis George put it, success in addressing everyday concerns can engender confidence in pursuing more transformative goals.
