On the night of June 24, 2025, a political tremor shook New York City. Zohran Mamdani, a 33-year-old, first-term state assemblyman from Queens and a self-described democratic socialist, claimed a stunning victory in the Democratic primary for mayor.
His defeat of the heavily favored former Governor Andrew Cuomo, a titan of the Democratic establishment, was immediately labeled a political earthquake. Yet, viewed through the long lens of American history, Mamdani’s rise is not an isolated shock but the latest chapter in a recurring story.
His victory, fueled by a platform addressing the city’s crushing cost of living, represents a powerful tremor along a fault line that has run through American politics for more than a century: the periodic and often potent appeal of the socialist candidate.
Defining Democratic Socialism in America
In the American political context, “democratic socialism” is a philosophy that supports a socially or collectively owned economy operating alongside a robust democratic political system. Proponents like Senator Bernie Sanders and organizations like the Democratic Socialists of America (DSA) emphasize economic and workplace democracy, distinguishing their vision from the authoritarian, state-controlled systems of Marxist-Leninist states.
This distinction is vital, as the label “socialist” itself is a contested political battleground. The appeal of candidates like Mamdani often stems not from a widespread voter commitment to a specific ideology, but from their direct, tangible proposals to solve immediate crises—proposals that are then branded, by both supporters and detractors, as socialist.
This report seeks to answer fundamental questions that resurface with each new socialist success. Under what specific social and economic conditions have American voters found these candidates and their platforms appealing? What are the common threads connecting these historical moments of socialist resurgence? And, most critically, when these candidates are elected to office, what has their actual, verifiable record been in terms of governance and legislative accomplishment?
By examining the modern test case of Zohran Mamdani and placing him within a rich historical context, we can illuminate the enduring and evolving role of the socialist candidate in the American experiment.
The Modern Test Case: Zohran Mamdani’s Ascent in New York
The Candidate: From Housing Counselor to Mayoral Nominee
Zohran Mamdani’s biography is a portrait of global and local influences. Born on October 18, 1991, in Kampala, Uganda, to parents of Indian descent—the acclaimed filmmaker Mira Nair and the postcolonial academic Mahmood Mamdani—his early life was spent in Uganda and, briefly, South Africa.
At age seven, his family settled in New York City, where he was raised in the Morningside Heights neighborhood of Manhattan. He has described his upbringing as “privileged,” an experience that gave him an awareness of the vast economic disparities in the city he called home.
After graduating from the Bronx High School of Science and Bowdoin College with a degree in Africana studies, Mamdani’s path was varied, including a stint as a hip-hop artist under the name Mr. Cardamom.
However, his political trajectory was decisively shaped by his work as a foreclosure prevention housing counselor in Queens. In this role, he assisted low-income homeowners, primarily people of color, in their battles against banks to avoid eviction.
Mamdani has repeatedly cited this experience as the catalyst for his entry into electoral politics, stating that it brought him “face-to-face with the reality that this housing crisis… was not natural to our lives, but instead a choice.” This perspective—that economic hardship is a consequence of policy decisions, not an inevitability—became the cornerstone of his political identity.
His early activism, which included co-founding a chapter of Students for Justice in Palestine at Bowdoin, also foreshadowed the progressive and often controversial foreign policy stances he would later adopt.
The Platform: A Direct Response to the Urban Affordability Crisis
Mamdani’s mayoral platform was a direct and unambiguous response to the cost-of-living crisis afflicting millions of New Yorkers. Rather than focusing on abstract ideology, his campaign presented a suite of concrete, easily understood proposals aimed at providing immediate economic relief. Each policy plank was designed to address a specific financial pressure point for working-class families.
Housing: At the heart of his agenda was a pledge to “Freeze the Rent” for the city’s more than two million residents in rent-stabilized apartments. This was a direct rebuke of recent rent increases approved by the city’s Rent Guidelines Board and a response to the reality that nearly a quarter of his own Assembly district’s residents spend half their income on rent.
He also proposed the construction of 200,000 new, permanently affordable housing units over ten years.
Transportation: Building on a legislative success, Mamdani called for making all city buses permanently fare-free. This proposal aimed to make public transit universally accessible and address the fact that New York’s buses are the slowest in the nation.
Affordability: To combat rising food prices, he proposed creating a network of city-owned grocery stores designed to operate at low margins, not for profit. Another major plank was the implementation of universal, no-cost childcare for every New Yorker from ages 6 weeks to 5 years, a policy designed to alleviate one of the largest expenses for young families and raise the wages of childcare workers.
Funding: To pay for this ambitious agenda, Mamdani proposed a $10 billion tax hike targeting large corporations and the city’s wealthiest residents. His plan would raise the corporate tax rate to match New Jersey’s 11.5% and implement a new tax on individuals earning over $1 million annually.
Anatomy of a Modern Coalition: Expanding the Electorate
Mamdani’s victory was not just a result of his platform but also of a sophisticated campaign strategy that successfully expanded the electorate. His campaign demonstrated a powerful model for modern progressive politics by mobilizing two key, often underrepresented, constituencies: young people and immigrant communities.
Analysis of election data revealed a remarkable surge in participation among young voters. In neighborhoods with high concentrations of residents aged 18-34, such as Astoria, Greenpoint, and Bushwick, voter turnout was two to three times higher than in the 2021 mayoral primary.
This youth mobilization was a direct result of a campaign that spoke to their primary concern—the cost of living—and used savvy, energetic social media to build an enthusiastic base.
Simultaneously, Mamdani’s campaign executed a meticulous multilingual and multicultural outreach effort. His own identity as a Ugandan-born, South Asian Muslim immigrant, fluent in both Hindi and Urdu, was a significant asset.
The campaign produced materials and social media videos in languages including Hindi, Urdu, Arabic, and Bengali, speaking directly to immigrant communities about the material issues affecting their lives. This strategy paid dividends, as Mamdani won by large margins in South Asian neighborhoods in Queens, Latino neighborhoods across the city, and even made inroads in Chinese communities in Flushing and Chinatown.
This success demonstrates a potent fusion of identity-based outreach and class-based economic appeals. Instead of treating these as separate political tracks, the Mamdani campaign used the candidate’s identity and language skills as the vehicle to deliver a universal message about shared economic struggles.
This allowed him to build a broad, multi-ethnic, working-class coalition that proved more powerful than the traditional Democratic power bases, such as some unions and older Black voters in certain neighborhoods, that had lined up behind Andrew Cuomo.
The Albany Record: A Pragmatic Assessment
During the primary campaign, Andrew Cuomo attacked Mamdani’s legislative record, claiming he had only passed three bills in his four-and-a-half years in the New York State Assembly. While factually correct, this criticism overlooks the nuances of legislative impact.
A closer examination reveals a record focused on increasing government transparency and constituent services, alongside a strategic use of his position to advance broader policy goals.
The three bills Mamdani sponsored that were signed into law were:
Assembly Bill A6267 (2021): This law created a pilot program to make public hearings held by state regulatory agencies more accessible and participatory. It allowed for public questioning of agency staff and more flexible scheduling, including evenings and weekends.
Assembly Bill A8796 (2022): This follow-up bill further increased public participation by lowering the number of petitioners required to trigger a public hearing from 500 to 125 for certain agencies.
Assembly Bill A7113 (2023): A hyper-local bill specific to his Astoria district, this law amended the state’s liquor laws to allow for the sale of alcohol at the Museum of the Moving Image, which is located near a school.
Beyond these specific laws, Mamdani’s legislative influence is evident in his advocacy for fare-free buses. An idea from his “Fix the MTA Act” was not passed as a standalone bill but was instead incorporated into the state budget, creating a successful one-year pilot program for fare-free bus routes in each borough.
This demonstrates a common path to legislative impact in a large body like the 150-member New York State Assembly, where influencing budget negotiations can be as significant as passing individual bills.
His record also includes protest votes against state budgets he felt were insufficient in funding social programs, such as childcare and public universities.
Historical Precedents: The Conditions for Socialist Appeal
The appeal of socialist candidates in the United States is not a recent development. It’s a cyclical phenomenon, gaining traction during specific periods of profound social and economic turmoil when the existing political and economic systems appear to be failing large segments of the population.
These moments of crisis expose deep-seated inequalities and corruption, making voters more receptive to candidates who offer systemic critiques and bold, government-led solutions.
The Progressive Era: A Reaction to Industrial Capitalism
The Gilded Age of the late 19th century was a period of unprecedented industrial growth, but it came at a tremendous social cost. The rise of massive corporate trusts, or monopolies, concentrated immense wealth and power in the hands of a few “robber barons.”
For ordinary Americans, this era was defined by brutal working conditions, rampant child labor, overcrowded and unsanitary urban slums, and pervasive political corruption that left government unwilling or unable to regulate industry. This widespread social distress created a powerful demand for reform, opening a significant political space for socialist ideas to take root.
Case Study: Victor Berger and Milwaukee’s “Sewer Socialists”
The most successful and enduring example of municipal socialism in American history emerged from this era in Milwaukee, Wisconsin. Led by Victor L. Berger, an Austrian immigrant, newspaper editor, and the first Socialist ever elected to the U.S. Congress in 1910, Milwaukee’s socialists built a formidable political organization.
Their power was grounded in a strong alliance with the city’s labor movement and its large German-American population. Rather than focusing on revolutionary rhetoric, they championed practical, tangible improvements to city life, earning them the nickname “Sewer Socialists.”
Their record of clean, efficient governance was a direct rebuke to the widespread corruption of the time. Under Socialist mayors like Emil Seidel and Daniel Hoan, the city:
- Established an extensive and nationally recognized public parks system
- Created municipally owned water and power systems
- Improved sanitation systems and public health inspections
- Founded the Milwaukee Continuation School, which evolved into the Milwaukee Area Technical College
On the national stage, Berger used his congressional platform to introduce the first-ever bill for federal old-age pensions. While it didn’t pass at the time, this radical proposal planted the seed for what would, two decades later, become the Social Security Act—a cornerstone of the American social safety net.
The Great Depression: Mainstreaming Radical Ideas
The catastrophic economic collapse of the Great Depression represented the most profound crisis of American capitalism. The stock market crash of 1929 triggered a decade of mass unemployment that reached 25%, widespread bank failures, farm and home foreclosures, and immense human suffering.
The crisis shattered public faith in the prevailing ideology of laissez-faire capitalism and created an urgent demand for government intervention on a massive scale.
This environment provided the political will for President Franklin D. Roosevelt’s New Deal. While Roosevelt was not a socialist, his administration enacted a series of sweeping government programs that had long been championed by the Socialist Party.
Policies such as Social Security, unemployment insurance, federal jobs programs like the Works Progress Administration (WPA), and laws protecting workers’ rights to organize were all core tenets of the socialist platform that had been dismissed as radical just years earlier.
The Great Depression thus serves as the clearest example of how a systemic crisis can rapidly move socialist-inspired ideas from the political fringe to the center of American public policy.
The Post-2008 Financial Crisis: A New Generation’s Discontent
The 2008 financial crisis and the ensuing Great Recession created a new moment of disillusionment that has shaped the politics of the 21st century. The crisis, triggered by the collapse of the subprime mortgage market, led to a massive government bailout of Wall Street banks.
The public perception that financial elites were rescued while millions of ordinary Americans lost their homes and jobs fueled a deep and lasting populist anger toward both the economic and political establishments.
This discontent manifested on both the right, with the rise of the Tea Party movement, and on the left, with the Occupy Wall Street protests. For many millennials and members of Gen Z, who came of age during this period of economic precarity and witnessed the perceived injustices of the bailout, the crisis fostered a profound skepticism of capitalism.
This created the fertile ground for the dramatic resurgence of democratic socialism in the 2010s, most visibly embodied by the presidential campaigns of Bernie Sanders and the subsequent election of a new generation of socialist leaders like Alexandria Ocasio-Cortez and Zohran Mamdani.
The Torchbearers: Key Figures in American Socialism
Throughout these periods of crisis, charismatic and principled leaders have emerged to give voice to the socialist movement. These figures have served not only as candidates but as educators and organizers, introducing radical ideas into the public discourse and building coalitions that have reshaped the American political landscape.
Their success is often measured less by elections won and more by their long-term influence on the trajectory of progressive policy.
Eugene V. Debs: The Conscience of a Movement
Eugene V. Debs stands as the foundational figure of the American socialist movement. A railroad worker and labor organizer from Terre Haute, Indiana, he co-founded the American Railway Union, one of the nation’s first industrial unions.
His experience leading the Pullman Strike of 1894, which was brutally suppressed by federal troops, and his subsequent imprisonment, convinced him that workers needed their own political party.
As the five-time presidential candidate for the Socialist Party of America, Debs used his campaigns as national forums for education. His platform consistently advocated for ideas that were considered revolutionary at the time but are now widely accepted, including:
- Women’s suffrage
- The abolition of child labor
- An eight-hour workday and industrial safety laws
- Public ownership of railroads and utilities
- A system of social insurance against unemployment and accidents
Debs’s most iconic moment came in 1920 when he ran for president from a cell in the Atlanta Federal Penitentiary. He had been convicted under the Espionage Act for delivering a speech opposing U.S. involvement in World War I.
Campaigning as “Convict No. 9653,” he received nearly one million votes, a powerful testament to his moral authority and the resonance of his message of principled dissent.
Bernie Sanders: Bringing Socialism into the Mainstream
For decades after Debs, socialism remained on the fringes of American politics. That changed with the career of Bernie Sanders. Beginning his political life in Vermont’s anti-war Liberty Union Party in the 1970s, Sanders was elected mayor of Burlington in 1981, defeating a five-term incumbent Democrat.
After serving in the U.S. House of Representatives, he was elected to the Senate in 2006, eventually becoming the longest-serving independent in congressional history.
His 2016 and 2020 presidential campaigns were transformative events in American politics. They re-introduced democratic socialism to a new generation and demonstrated the mass appeal of policies like Medicare for All, tuition-free public college, and a Green New Deal.
Sanders successfully framed these ideas not as foreign imports but as the logical continuation of Franklin D. Roosevelt’s New Deal and his proposed “Second Bill of Rights,” which included rights to a job, healthcare, and education.
Despite his reputation as an uncompromising outsider, Sanders has a notable record of legislative effectiveness. During the period of Republican control of the House from 1995 to 2007, he earned the nickname the “amendment king” for passing more roll-call amendments than any other member.
As chairman of the Senate Committee on Veterans’ Affairs, he worked across the aisle in 2014 to pass a major piece of bipartisan legislation to reform the VA health care system.
Alexandria Ocasio-Cortez and “The Squad”: A New Generation of Leadership
The energy and ideas of the Sanders movement directly fueled the rise of a new generation of democratic socialist leaders, most prominently Alexandria Ocasio-Cortez. A former organizer for Sanders’ 2016 campaign, Ocasio-Cortez achieved a stunning upset victory in the 2018 Democratic primary, defeating a 10-term incumbent and chair of the House Democratic Caucus.
Taking office at age 29, she became the youngest woman ever elected to Congress and, along with Rep. Rashida Tlaib, one of the first female members of the Democratic Socialists of America (DSA) to serve in that body.
She and other progressive members, known as “The Squad,” have become influential voices on the left wing of the Democratic Party.
Her signature legislative proposal has been the Green New Deal resolution. While the resolution itself didn’t pass, it fundamentally shifted the national conversation on climate change by linking environmental action with economic justice, job creation, and infrastructure investment.
The framework and ambition of the Green New Deal are widely credited with shaping the climate and clean energy provisions of the Inflation Reduction Act of 2022, the largest climate investment in U.S. history.
Her legislative record also includes tangible, bipartisan achievements, such as securing an amendment that shifted $5 million from the “war on drugs” to opioid addiction treatment and working with Senator Chuck Schumer to create the COVID-19 Funeral Assistance Program, which has reimbursed over a billion dollars to families who lost loved ones during the pandemic.
The careers of these figures reveal a distinct pattern in American politics. Socialist candidates often act as an ideological incubator for the Democratic Party. They introduce and popularize policies on the political fringe that are initially dismissed as radical.
Decades later, particularly in response to a crisis, moderated versions of these same policies are often adopted by the Democratic mainstream and become part of the national consensus. The journey of ideas like social security, a minimum wage, and large-scale climate investment from socialist platforms to federal law suggests that the influence of these torchbearers extends far beyond their own legislative victories.
The Balance Sheet: Assessing the Record of Elected Socialists
An objective evaluation of the record of elected socialists in the United States requires a nuanced look at both their tangible successes and the significant challenges and criticisms they have faced. Their impact is most clearly seen at the municipal level, where practical governance often outweighs ideological purity, but their efforts have consistently encountered structural barriers and potent economic counterarguments.
Successes and Lasting Impact: From Sewers to Solar Panels
When in power, particularly in city governments, socialist officials have often compiled a record of effective, clean, and innovative governance. By focusing on the direct provision of public goods and services, they have left a lasting mark on the urban landscape.
The “Sewer Socialists” of Milwaukee are the prime example, pioneering public ownership of utilities, creating comprehensive park systems, and championing public health and education at a time when many city governments were mired in corruption. This legacy of practical, popular reform has been a recurring theme.
| Official | Office Held | Key Accomplishment(s) |
|---|---|---|
| Emil Seidel, Daniel Hoan | Mayors of Milwaukee | Established comprehensive public parks system, municipal water/power, improved sanitation, founded precursor to Milwaukee Area Technical College |
| Victor Berger | U.S. Representative | Introduced first federal old-age pension bill; secured congressional investigation into the 1912 Lawrence textile strike |
| Bernie Sanders | U.S. Representative/Senator | Passed more roll-call amendments in a Republican-led House than any other member (1995-2007); passed major bipartisan VA reform legislation (2014) |
| Alexandria Ocasio-Cortez | U.S. Representative | Introduced Green New Deal framework, influencing climate provisions in the Inflation Reduction Act; secured COVID-19 funeral assistance program |
| Zohran Mamdani | NYS Assemblymember | Passed legislation to increase public participation in agency rulemaking; secured funding for a fare-free bus pilot program in NYC |
Challenges, Failures, and Criticisms: The Limits of the Possible
Despite these successes, the path for socialist politicians in America is fraught with obstacles. The most significant is the nation’s rigid two-party, winner-take-all electoral system. This structure makes it exceedingly difficult for third parties to gain a lasting foothold, as voters are often reluctant to “waste” their vote on a candidate with little chance of winning.
This has historically forced socialists to either run within the Democratic Party, as Mamdani and Ocasio-Cortez have, or as independents who caucus with Democrats, like Sanders.
This leads to a central paradox: to achieve electoral success, socialists often must moderate their platforms, focusing on popular reforms rather than the more radical goal of abolishing capitalism. In doing so, they can become nearly indistinguishable from “advanced progressives,” achieving practical gains at the expense of ideological purity.
Furthermore, socialist policies face potent and long-standing economic criticisms. Mainstream economic theory argues that centralized planning is inherently inefficient because it lacks the price signals generated by free markets, which are essential for the rational allocation of resources.
Specific policies are also targeted. Critics contend that rent freezes, a key plank of Mamdani’s platform, ultimately reduce the housing supply by disincentivizing new construction and maintenance.
Public ownership of industries is criticized for potentially leading to stagnation and inefficiency due to the absence of competition and the profit motive. High taxes on corporations and the wealthy, critics warn, could lead to capital flight, as businesses and high-income earners relocate to lower-tax jurisdictions.
Finally, while Milwaukee’s socialists are lauded for their fiscal management, other cities that have adopted more expansive government programs have faced severe fiscal challenges. Structural deficits and massive unfunded pension liabilities in cities like Chicago and Los Angeles are sometimes cited as cautionary tales of the long-term costs associated with extensive public sector commitments.
The story of the socialist candidate in America is one of persistent influence rather than dominant power. The primary obstacle to their success may not be voter opposition to their specific policies—many of which, like paid family leave and a higher minimum wage, are broadly popular.
Instead, the barriers are the structural and cultural foundations of American politics: a constitutional system designed to thwart radical change and a deep-seated cultural preference for individualism and anti-statism.
This reality suggests that the most viable path for socialist influence in the United States is not to build a separate, winning third party, but to operate as an ideological engine within the Democratic Party coalition—pushing its center of gravity leftward, one crisis and one candidate at a time.
