Zohran Mamdani, New York City’s democratic socialist mayor, represents a major shift inside Democratic politics. He has been called a socialist, a communist, an antisemite and a threat to capitalism. His supporters often say those labels are unfair. His critics often say they are obvious. The truth is more complicated.
In Enlightenment Now, psychologist Steven Pinker describes people as often behaving less like neutral investigators than advocates, “marshaling evidence that confirms their convictions while dismissing evidence that contradicts them.” Mamdani is exactly the kind of politician who invites that kind of thinking. His politics really are well to the left of most Democrats, especially on economics and Israel. But some of the strongest claims about him go further than the public record supports.
So the useful question is not simply whether Mamdani is “radical.” It is this: What does he actually believe, how different is that from mainstream Democratic politics, and how well do his views hold up against the evidence?
Is Mamdani a Communist?
No. Mamdani calls himself a democratic socialist and rose politically with strong support from the Democratic Socialists of America. So calling him a socialist is fair. Calling him a communist is not.
Communism traditionally means replacing most private ownership of businesses and industry with collective or government ownership. Communist systems have also often relied heavily on central economic planning. That is not what Mamdani is proposing for New York. Private businesses still operate. Landlords still own buildings. Developers still build housing. Banks and Wall Street remain private. His administration has even pushed reforms meant to make it easier for small businesses to deal with permits, fees and paperwork.
But that does not mean Mamdani is just an ordinary liberal. A traditional moderate Democrat usually accepts capitalism as the basic system and tries to improve it with regulations, taxes and social programs. Mamdani is more skeptical of capitalism itself. He believes private economic power can give landlords, corporations and employers too much control over ordinary people’s lives.
That difference shows up in his policies. His administration wants far more public and affordable housing. It supports rent freezes for some apartments. It has also backed city-supported grocery stores as an alternative in the food market. His administration has set a goal of creating 200,000 new affordable homes and preserving another 200,000 over 10 years, using a mix of public investment, subsidies, zoning changes and private-sector construction.
That is more government involvement than most moderate Democrats would normally support. Still, it is not an attempt to abolish private grocery stores, private housing or private business. So “anti-capitalist” can be a fair description if it means Mamdani thinks capitalism has serious built-in problems and wants a bigger public role in the economy. It would be misleading if it meant he wants to eliminate markets or private property altogether.
How Different Are His Economic Ideas?
The easiest way to think about this is to forget the labels for a moment. Almost every wealthy democracy today uses a mixed economy. Most goods and services are produced by private businesses, while government regulates markets, provides social programs and sometimes supplies services directly.
Markets are useful because competition can lower prices, encourage innovation and give people choices. But markets can also fail. A company can pollute without paying the full cost. A monopoly can overcharge customers. Basic scientific research may attract too little private investment. Health care can be difficult to treat like an ordinary consumer purchase.
Government can fail too. Public agencies can waste money. Rules can become unnecessarily complicated. Subsidies can keep inefficient programs alive long after they stop making sense. The real question is therefore not “capitalism or socialism?” It is where markets work well and where government can do better.
Housing is a good example. Mamdani wants a major increase in housing construction. That has a strong economic logic because one important reason housing becomes expensive is that too many people are competing for too few homes. His support for rent freezes is more controversial. A rent freeze can help tenants immediately by stopping their rent from rising, but strict rent controls can also reduce incentives to maintain rental properties or build new ones. How serious those effects become depends heavily on how the policy is designed.
Mamdani is therefore trying to do two things at once: protect current tenants now and build much more housing for the future. The first is more economically disputed. The second has a stronger case.
His grocery plan raises a similar question. The city is moving forward with city-run grocery stores, beginning with a location in the Bronx. If a neighborhood lacks affordable food options, government involvement may be justified. But groceries are also the kind of business where private competition can often work reasonably well. Before deciding that the city should provide groceries directly, an evidence-based approach would ask what the underlying problem is. Is there too little competition? Are families unable to afford food? Are zoning or transportation barriers keeping stores away?
Mamdani is more willing than a moderate Democrat to try government-run or government-backed solutions. That is a real difference. It does not mean he is always wrong. It means he starts from a more skeptical view of markets.
His public language can also make these economic choices sound simpler than they really are. Mamdani often talks about tenants versus landlords, workers versus corporations and public need versus private profit. That can draw attention to real abuses, but it can also leave out other parts of the story, such as shortages, incentives, investment and the possibility that government rules can create new problems.
Mamdani is often very good at drawing attention to problems that mainstream politics has ignored or downplayed. But he can spend less time on the tradeoffs and facts that make his preferred solutions harder. That does not make his diagnosis wrong. It means his public case can be more complete on the problem than on the costs of the solution.
His actual governing agenda is somewhat more complicated than that rhetoric. He is pushing for more public involvement, but he is also trying to build more housing and make it easier for small businesses to operate. Because his administration is still relatively new, many judgments about these policies are judgments about their design and evidence from similar policies elsewhere. Their long-term results under Mamdani are not yet known.
Mamdani’s economic disagreements with moderate Democrats are mostly about how much government should do. On Israel, the disagreement is more basic: what rights Jews and Palestinians have, and what kind of state Israel should be.
Why Is Israel Such a Bigger Issue?
This is where Mamdani is much farther from the position most mainstream Democrats have held for decades. A typical Democrat can strongly criticize Israeli Prime Minister Benjamin Netanyahu, oppose settlement building in the West Bank and criticize Israel’s conduct in Gaza while still believing that Israel should remain a Jewish state.
Mamdani’s disagreement goes deeper. He supports BDS, which stands for Boycott, Divestment and Sanctions, a movement that uses economic pressure against Israel. He has also declined to support Israel’s right to exist specifically as a Jewish state.
This is where some terminology can make the debate sound more complicated than it needs to be. Zionism, in simple terms, is the belief that Jews should have a homeland in Israel where they can govern themselves. That does not necessarily mean a religious government.
Mamdani has said Israel has a right to exist, but he has resisted saying it must exist specifically as a Jewish state. His emphasis is on equal rights for everyone, regardless of religion or ethnicity.
That principle is easy to understand. The harder question is what it means for Israel’s identity. Many Jews see Israel not simply as another country, but as a place where Jews can govern themselves and have a refuge if they face persecution elsewhere. Supporting that idea does not necessarily mean supporting religious rule or unequal rights for non-Jews.
So the real disagreement is not simply “Jewish state versus equal rights.” Those goals do not automatically conflict. The difficult question is whether Israel can remain a country with a distinctly Jewish character while also guaranteeing equal rights to everyone who lives there.
Mamdani’s answer puts much more weight on the equal-rights side of that question. What remains less clear is how his approach would protect the Jewish desire for a secure place of self-government at the same time. That tension provides the backdrop for another controversy: Mamdani’s response to the phrase “globalize the intifada.”
“Intifada” means uprising. Some pro-Palestinian activists use the word to mean resistance to Israeli rule. But for many Jews and Israelis, it immediately brings to mind the Second Intifada, a period in the early 2000s that included suicide bombings and other attacks that killed Israeli civilians.
Mamdani initially declined to condemn the phrase. He later said he would discourage people from using it. It would be unfair to assume that everyone who says “globalize the intifada” is calling for violence against Jews. But it would also be unreasonable to pretend the phrase has no violent history.
Mamdani’s response does not show that he hates Jews. It does raise a fair question about whether he gave enough weight to why that language sounds threatening to many Jews. That brings us to an important distinction: being anti-Zionist and being antisemitic are not the same thing. A person can oppose Israel having a specifically Jewish national identity without being prejudiced against Jews. But anti-Zionist politics can become antisemitic when they rely on anti-Jewish stereotypes, blame Jews collectively for Israel’s actions or excuse hostility toward Jews.
Mamdani’s rhetoric is one kind of evidence. The people he chooses to hire and endorse are another.
What About the People Around Him?
This is one of the stronger arguments made by Mamdani’s critics, but it needs to be handled carefully. Not every controversial associate is equally important.
Someone who supports BDS or strongly criticizes Israel is not automatically antisemitic. Someone who uses explicit stereotypes about Jews is a much more serious case. The strongest evidence against Mamdani himself would be if he knowingly kept promoting people after learning they had expressed clear anti-Jewish prejudice.
Catherine Almonte Da Costa is a good example. Mamdani chose her to lead his Office of Appointments, an important job involving staffing his administration. Old social-media posts later surfaced that the Anti-Defamation League said contained classic antisemitic tropes. One referred to “money-hungry Jews.” That phrase is not criticism of Israel. It invokes a centuries-old antisemitic stereotype about Jews and money.
Da Costa apologized and resigned. Mamdani accepted her resignation. The available reporting does not establish that he knew about the old posts when she was selected. That raises a legitimate question about vetting. It does not show that Mamdani knowingly chose someone because of antisemitic views.
Darializa Avila Chevalier is a different case. She attended a pro-Palestinian rally in New York on Oct. 8, 2023, one day after Hamas attacked Israel. Mamdani later endorsed her for Congress. The timing matters. This was immediately after Hamas had killed and kidnapped Israeli civilians, not simply a protest held later in response to months of Israeli military operations in Gaza.
Attending the rally does not prove that Chevalier supported every chant or statement made there. But Mamdani’s later endorsement does show that her attendance was not enough to disqualify her in his eyes. Those choices matter because appointments and endorsements are decisions, not random associations. But even repeated poor judgment is not the same thing as personal prejudice. That is the distinction at the heart of the antisemitism charge.
So Is Mamdani Antisemitic?
The evidence supports a more cautious answer than either side often gives. There is strong evidence that Mamdani’s politics are anti-Zionist. There is also real evidence that some of his rhetoric, appointments and endorsements have worried many Jewish New Yorkers.
His handling of “globalize the intifada” is one reason some Jewish critics question his judgment on rhetoric they see as threatening. But saying that Mamdani himself is antisemitic means something more specific. It means he is prejudiced against Jews because they are Jews. The public record does not firmly establish that.
There is evidence pointing the other way. Mamdani retained New York City’s Office to Combat Antisemitism and appointed Phylisa Wisdom, a Jewish communal leader, to run it. He has publicly said his administration will work to protect Jewish New Yorkers. Those actions do not prove what Mamdani privately believes, but neither do his political associations prove the opposite.
The conclusion should be allowed to change if new facts appear. If Mamdani repeatedly hired people while knowing they had made openly antisemitic statements, defended those statements after they became public, or treated Jewish groups differently because they were Jewish, the case against him would become much stronger. If he consistently rejects antisemitic rhetoric even when it comes from his own allies, the case would become weaker.
For now, the fairest conclusion is this: There are good reasons to scrutinize Mamdani’s judgment around antisemitism, but the evidence does not firmly show that Mamdani himself is antisemitic.
Whether Mamdani is personally antisemitic is one question. Whether his view of Israel and Palestine is persuasive is another. To answer the second, the standard cannot just be what mainstream Democrats believe. It has to be what the history, the law and the facts on the ground actually show.
What Does the Evidence Say About Israel and Palestine?
The historical and legal record starts with one basic fact: both Jews and Palestinians have deep ties to the land and legitimate claims to security and self-government.
Jews have a deep historical connection to the land and understandable reasons to want a place where they can govern and protect themselves. Jewish history includes centuries of persecution and, most catastrophically, the Holocaust. Israeli civilians have also faced terrorism, rocket attacks and hostage-taking.
Palestinians also have a deep historical connection to the land. They have lived for generations without a fully sovereign country of their own, and many have experienced military occupation, settlement expansion, displacement and restrictions on movement and political freedom. Both realities matter.
Hamas’s Oct. 7 attack, including attacks on civilians and hostage-taking, cannot be justified by Palestinian suffering. But Hamas’s crimes also do not give Israel unlimited authority over Palestinian civilians.
Israel’s occupation and settlement policies have drawn serious legal findings. In 2024, the International Court of Justice concluded in an advisory opinion that Israel’s continued presence in the occupied Palestinian territories was unlawful and said new settlement activity must stop and settlers should be evacuated from the occupied territories.
Israel’s conduct in Gaza has also faced serious international legal scrutiny. The International Criminal Court issued arrest warrants for Netanyahu and former Defense Minister Yoav Gallant over alleged war crimes and crimes against humanity. Those warrants are not convictions and do not prove guilt. They mean judges found enough evidence, at that stage of the case, to issue arrest warrants.
Taken together, the history, international law and a consistent concern for equal rights point toward a basic principle: Israeli Jews and Palestinians both deserve security, political rights and the ability to govern themselves. Neither side has the right to permanently rule the other.
That does not tell us exactly what the final political solution should look like. One option is two states, Israel and Palestine. Another is a single democratic state where everyone has equal rights. Some people propose a looser confederation.
Each option has serious problems. A single state sounds simple because everyone would vote under one government, but it would also ask two deeply distrustful national groups, with a long history of violence and competing claims to land and refugees, to share one political system. Two states allow each people to govern itself, but decades of settlement growth, territorial fragmentation and failed negotiations have made that solution difficult to achieve.
For decades, the United States has treated Israel’s security as a major foreign-policy commitment. It has also supported the idea of a Palestinian state reached through negotiations between Israelis and Palestinians.
The evidence does not give us a perfect political answer. But it does tell us what any reasonable answer has to protect: Jewish security and self-government, Palestinian security and self-government, and equal basic rights for both.
Against that standard, Mamdani’s record is mixed. Some of his criticisms of Israel are strongly supported by international legal findings and by documented Palestinian suffering, particularly his focus on settlement expansion, Palestinian rights and accountability for Israeli conduct.
His position becomes harder to defend when the question turns to Israel’s Jewish national identity. Mamdani argues that a state should guarantee equal rights rather than give preference to one ethnic or religious group. But that leaves an important practical question unresolved: How can Jewish self-government and Palestinian self-government both be protected?
A similar pattern appears in the way Mamdani talks about Israel and Palestine. He speaks forcefully about Palestinian suffering, Israeli wrongdoing and equal rights. Those are real issues. But he tends to spend less time on Israeli security fears, Hamas’s responsibility for attacks on civilians and the reasons many Jews see Israel as necessary for their own safety.
That does not make his criticism of Israel false. It does mean that hearing Mamdani alone can leave a listener with only part of the picture.
Sometimes moving away from the mainstream brings him closer to the evidence. Sometimes it brings him farther away.
So How “Radical” Is Mamdani?
Compared with the American political center, Mamdani really is far to the left. But “radical” only tells us that an idea is far from the mainstream. It does not tell us whether the idea is right.
On economics, Mamdani identifies real problems such as high housing costs and economic insecurity. Some of his answers, especially building much more housing, have strong logic behind them. Others, such as strict rent controls or government entry into markets that may already be competitive, are more debatable.
On Israel, some of his criticisms are well supported by evidence. But his anti-Zionist politics can give too little weight to legitimate Jewish concerns about security and having a place where Jews can govern themselves.
On antisemitism, there are real reasons to question his judgment and some of the people he has chosen to support. But the evidence does not currently establish that he personally hates or is prejudiced against Jews.
There is also an important difference between radical ideas and radical methods. Mamdani wants larger changes than most Democrats do, but he is trying to achieve them through elections, laws, budgets and ordinary government institutions. He is not leading a revolutionary movement to overthrow the political system.
The debate over Mamdani shows the limits of political labels. They can tell us where a politician sits, but not whether his ideas are sound. Some of Mamdani’s arguments hold up well under scrutiny. Others are much weaker. The same is true of the accusations made against him.
The more useful question is not what label fits Mamdani best, but which of his claims the evidence supports, which it does not, and where the truth is more complicated than either side admits.
Evidence & Source Transparency
Evidence First shows its work. The article ends above; this section is included so readers can inspect the main sources behind the factual claims.
The list below does not source every sentence. It focuses on the factual claims most important to the argument.
1. Mamdani’s economic program
Claim or topic:
Mamdani’s agenda includes a large affordable-housing expansion, rent regulation, greater public involvement in the economy, and efforts to make it easier for small businesses to operate.
Source:
New York City Mayor’s Office
Source type:
Primary document / government record.
What it supports:
The administration’s housing goals and its description of how public investment, zoning, subsidies and private-sector construction would contribute to new affordable housing.
Important caveat:
These are government plans and goals, not proof that the policies will achieve their intended results. The article’s discussion of likely economic tradeoffs relies on broader economic evidence, not on the administration’s claims alone.
2. Mamdani’s position on Israel, BDS and “globalize the intifada”
Claim or topic:
Mamdani supports BDS, has declined to affirm Israel’s right to exist specifically as a Jewish state, and initially declined to condemn the phrase “globalize the intifada” before later saying he would discourage its use.
Source:
Associated Press
Source type:
Reputable journalism.
What it supports:
Mamdani’s stated positions and the political controversy surrounding his views on Israel and the phrase “globalize the intifada.”
Important caveat:
These statements establish Mamdani’s political positions and rhetoric. They do not, by themselves, establish hostility or prejudice toward Jews.
3. Catherine Almonte Da Costa
Claim or topic:
Mamdani selected Catherine Almonte Da Costa for a senior appointments role; old social-media posts later surfaced, including a reference to “money-hungry Jews,” after which she apologized and resigned.
Source:
Associated Press
Source type:
Reputable journalism.
What it supports:
The appointment, the substance of the old posts, Da Costa’s resignation and the available reporting about Mamdani’s response.
Important caveat:
The available evidence does not establish that Mamdani knew about those posts when he selected her. The episode is therefore stronger evidence about vetting than about Mamdani’s personal beliefs.
4. Darializa Avila Chevalier and the Oct. 8 rally
Claim or topic:
Darializa Avila Chevalier attended a pro-Palestinian rally in New York on Oct. 8, 2023, one day after the Hamas attack, and Mamdani later endorsed her for Congress.
Source:
City & State New York
Source type:
Reputable journalism.
What it supports:
Chevalier’s attendance at the rally and Mamdani’s later political support for her.
Important caveat:
Attendance at a rally does not establish agreement with every chant, statement or participant. The article treats the episode as evidence about Mamdani’s political judgment, not proof that he or Chevalier endorsed violence.
5. International Court of Justice ruling on occupation and settlements
Claim or topic:
In 2024, the International Court of Justice concluded that Israel’s continued presence in the occupied Palestinian territory was unlawful and said settlement activity should cease.
Source:
International Court of Justice
Source type:
Court ruling / primary legal document.
What it supports:
The article’s statement that serious international legal findings support scrutiny of Israel’s occupation and settlement policies.
Important caveat:
This was an advisory opinion, not a criminal judgment against individual Israeli officials. Legal findings about occupation and settlements also do not, by themselves, resolve the broader political debate over Israel’s legitimacy or the final form of an Israeli-Palestinian settlement.
6. International Criminal Court warrants
Claim or topic:
The International Criminal Court issued arrest warrants for Benjamin Netanyahu and Yoav Gallant over alleged war crimes and crimes against humanity.
Source:
International Criminal Court
Source type:
Court record / primary legal document.
What it supports:
The article’s statement that Israeli conduct in Gaza has faced serious international legal scrutiny.
Important caveat:
An arrest warrant is not a conviction and does not prove guilt. It means ICC judges concluded that the legal requirements for issuing a warrant had been satisfied at that stage.
7. Mamdani’s response to antisemitism
Claim or topic:
Mamdani retained New York City’s Office to Combat Antisemitism and appointed Jewish communal leader Phylisa Wisdom to lead it.
Source:
New York City Mayor’s Office
Source type:
Primary document / government record.
What it supports:
The article’s discussion of evidence that cuts against a simple conclusion that Mamdani is personally hostile toward Jews.
Important caveat:
An appointment cannot establish a politician’s private beliefs. It is relevant evidence about conduct and governing choices, which should be weighed alongside his rhetoric, associations and other actions.
8. Steven Pinker quotation
Claim or topic:
The article quotes Steven Pinker on the tendency to marshal evidence that confirms existing convictions while dismissing contradictory evidence.
Source:
Steven Pinker, Enlightenment Now.
Source type:
Primary published work.
What it supports:
The quotation provides the article’s methodological frame: political claims should be tested against evidence rather than accepted or rejected because they fit a preferred narrative.
Important caveat:
A direct publisher or book-preview link was not retained in the article’s source trail. For publication, the exact wording and page number should be checked against a copy of Enlightenment Now.
