Former Vice President Kamala Harris is not officially running for president in 2028. But her recent outreach to New York City Mayor Zohran Mamdani, one of the most visible democratic socialists in American politics, is already revealing where the Democratic Party’s internal pressure is moving.

According to Axios, Harris privately called Mamdani after his endorsed candidates swept several major New York primaries. She has also held meetings or conversations with other progressive figures, including pro-Palestinian activists connected to the Uncommitted Movement. Mamdani later confirmed that Harris had been “in touch” with him over the past few months, according to the Washington Examiner.

That does not mean Harris has become a democratic socialist. It does mean something politically important: a former vice president and likely 2028 contender now sees the socialist wing as too influential to ignore.

The old Democratic establishment used to treat democratic socialism as a side movement — loud, young, and useful for online energy, but not strong enough to control major elections. That assumption is breaking down. In New York, democratic socialist and socialist-aligned candidates are no longer merely protesting the party from outside. They are winning Democratic primaries from inside the party.

The New York primaries that changed the conversation

The Democratic Socialists of America’s New York City chapter backed a slate of candidates in the 2026 primaries. According to NY1, DSA-backed candidates won congressional, State Senate, and State Assembly races across the city.

The most important recent winners were:

Claire Valdez, New York’s 7th Congressional District. Valdez is a state assemblymember, union organizer, artist, and self-described democratic socialist. NYC-DSA describes her as a dual citizen of the Ysleta del Sur Pueblo Nation and the United States, a former low-wage worker, and a Columbia University worker who organized through UAW Local 2110. She won the Democratic primary for the seat long held by Rep. Nydia Velázquez, defeating a field that included Brooklyn Borough President Antonio Reynoso. Ballotpedia News reported that Valdez defeated Vichal Kumar, Antonio Reynoso, and Julie Won.

Darializa Avila Chevalier, New York’s 13th Congressional District. Avila Chevalier is an Afro-Latina organizer, UAW member, daughter of Dominican immigrants, and investigator at Neighborhood Defender Services of Harlem. NYC-DSA says she ran on “babies, not bombs,” housing for all, and abolishing ICE. Her win was especially significant because she defeated incumbent Rep. Adriano Espaillat, a powerful Democrat and chair of the Congressional Hispanic Caucus. NY1 reported that Avila Chevalier won the Democratic nomination in the 13th District.

Brad Lander, New York’s 10th Congressional District. Lander was not endorsed by NYC-DSA, but he was backed by Mamdani and became part of the broader socialist-aligned wave. He is a former New York City comptroller, former City Council member, and former mayoral candidate. Ballotpedia News reported that Lander defeated incumbent Rep. Dan Goldman in the Democratic primary.

Samantha Kattan, Assembly District 37 in Queens. Kattan is a tenant organizer, working parent, daughter of immigrants, and democratic socialist. She ran for the seat Claire Valdez left open while pursuing Congress. NY1 reported that Kattan defeated two other candidates in the Democratic primary.

David Orkin, Assembly District 38 in Queens. Orkin is an immigrant workers’ rights attorney, union organizer, and democratic socialist running in Ridgewood, Glendale, Woodhaven, Richmond Hill, and Ozone Park. His campaign emphasized tenant protections, labor power, childcare, healthcare, and transit. NY1 reported that Orkin defeated incumbent Jennifer Rajkumar.

Christian Celeste Tate, Assembly District 54 in Brooklyn. Tate is a community organizer and democratic socialist running to represent parts of Bushwick and East New York, including Cypress Hills and City Line. His campaign centered on housing, immigration, and public safety through community investment. NY1 reported that Tate defeated incumbent Erik Dilan.

Eon Huntley, Assembly District 56 in Brooklyn. Huntley is a father, retail worker, lifelong Brooklynite, democratic socialist, and former PTA president. His campaign leaned heavily on affordability, education, tenant power, and opposition to real estate influence. NY1 reported that Huntley defeated incumbent Stefani Zinerman.

Illapa Sairitupac, Assembly District 65 in Lower Manhattan. Sairitupac is a tenant organizer and anti-ICE activist in Lower Manhattan. His campaign called for social housing, higher taxes on the wealthy, immigrant protections, and the Tenant Opportunity to Purchase Act. NY1 reported that Sairitupac defeated several challengers.

Aber Kawas, State Senate District 12 in Queens. Kawas is a Palestinian community organizer, democratic socialist, and daughter of refugees running to represent parts of Astoria, Sunnyside, Woodside, Ridgewood, Maspeth, Long Island City, Elmhurst, Glendale, and Jackson Heights. Her campaign emphasized affordability, immigrant families, opposition to ICE, and free, fast, safe buses. NY1 reported that Kawas defeated Steven Raga.

Diana Moreno, Assembly District 36 in Queens. Moreno won earlier in 2026, in the special election to fill Zohran Mamdani’s former Assembly seat. Her official Assembly biography says she assumed office on February 4, 2026, less than twenty-four hours after winning the special election.

One DSA-backed candidate who should not be placed in the winner category is Conrad Blackburn. Blackburn challenged Assemblymember Jordan Wright in Assembly District 70, but Spectrum News reported that Wright defeated Blackburn in the Democratic primary.

Why Harris’s outreach matters

Harris’s call to Mamdani came after these victories. That timing matters.

In a normal party environment, a former vice president might keep distance from a faction that openly identifies with socialism. Instead, Harris appears to be doing the opposite: opening lines of communication with the faction that is gaining activist energy, youth support, and primary power in deep-blue districts.

This is not just about Harris. It is about the Democratic Party’s center of gravity.

A generation ago, socialism was a toxic word in mainstream American politics. Today, it is a label ambitious candidates use in New York City, Denver, and other urban Democratic strongholds. Pew Research Center found that about a third of Democrats say they like political leaders who identify as democratic socialists. Pew also found stronger support among younger Democrats, white Democrats, and highly engaged Democrats.

That is exactly the kind of voter bloc that shapes low-turnout primaries.

The problem with democratic socialism

Democratic socialism presents itself as a politics of compassion: cheaper rent, free buses, universal childcare, Medicare for All, social housing, and aggressive action against corporations. Those promises sound attractive because they speak to real problems. Housing is expensive. Healthcare is expensive. Wages have not kept up with the pressure many families feel.

But democratic socialism’s danger is that it offers government control as the answer to nearly every hardship.

Its basic instinct is not to expand ownership, entrepreneurship, local business, private employment, or family independence. Its instinct is to centralize power: tax more, regulate more, redistribute more, nationalize or socialize more, and replace private decision-making with political decision-making.

That is why the movement is dangerous even when it uses soft language. It does not usually arrive saying it wants government domination. It arrives saying it wants “affordability,” “equity,” “public investment,” and “economic justice.” But behind those words is a worldview that treats private enterprise with suspicion and treats government as the moral owner of society’s resources.

The problem is not that every democratic socialist proposal is equally radical. The problem is the direction of the philosophy. It shifts citizens from independence toward dependency. It shifts markets from competition toward political allocation. It shifts local communities from voluntary life toward bureaucratic management.

A healthy society needs government. It needs law, infrastructure, courts, policing, national defense, and a safety net for people who truly need help. But democratic socialism goes far beyond limited government. It tries to make the state the main engine of moral and economic life.

That is a mistake.

Why it keeps rising anyway

Democratic socialism is rising because many voters believe the current system has failed them. Rent is high. Groceries are high. Healthcare is unaffordable for many families. Young voters look at home prices and conclude that the old American promise is dead.

Socialists are exploiting that frustration.

Their message is simple: billionaires are the problem, landlords are the problem, corporations are the problem, police are the problem, ICE is the problem, and the solution is to hand more power to the government and activist institutions. It is a clean narrative. It gives voters villains. It gives struggling people someone to blame.

But simple narratives are not always true.

America’s failures are real, but the answer is not socialism. The answer is to rebuild the conditions that allow normal people to own property, start businesses, form families, live safely, and rise through work. That means cutting the cost of living, restoring public order, protecting borders, lowering barriers to housing construction, defending small business, and making government competent instead of larger.

Democratic socialism moves in the opposite direction. It makes every problem political. It turns economic frustration into class warfare. It treats enforcement of immigration law as cruelty. It treats policing as oppression. It treats private profit as exploitation. It treats the market as something to be defeated rather than repaired.

A warning for the Democratic Party

The Democratic establishment now has a problem it cannot dismiss. The socialist wing is no longer just a few famous national figures. It is becoming an organized bench of city, state, and congressional candidates who can win primaries in low-turnout, heavily Democratic districts.

That is why Harris’s outreach matters. It shows that national Democrats are not only watching the socialist rise; they may be adapting to it.

The question is whether the party will contain this movement or be transformed by it.

If Democratic leaders keep treating the socialist wing as the future, they should not be surprised when the party becomes more hostile to capitalism, more hostile to immigration enforcement, more hostile to policing, more hostile to Israel, and more committed to permanent government expansion.

The rise of democratic socialism is not just a New York story. New York is the warning flare.

Kamala Harris’s call to Mamdani was more than a courtesy call. It was a signal that the Democratic Party’s next great internal battle has already begun.
