Democratic Socialism
The label he chose for himself — and the one his critics chose for him. Both are presented, attributed.
In his own words
Mamdani is a member of the Democratic Socialists of America, which he joined in 2017. His clearest statement of the label came in his inaugural address on January 1, 2026: “I was elected as a democratic socialist and I will govern as a democratic socialist.” He continued: “Beginning today, we will govern expansively and audaciously. We may not always succeed, but never will we be accused of lacking the courage to try to those who insist that the era of big government is over.”
As a program, his democratic socialism centers public provision against the cost of living: universal childcare “for the many by taxing the wealthiest few,” fare-free buses, city-owned grocery stores, frozen rents, and a $30 minimum wage by 2030. The through line is government’s active role in reducing household costs — what his March 2026 childcare announcement called “what Wall Street would call a good investment.”
How supporters use the term
Supporters — including DSA, the Working Families Party, and endorsers like Bernie Sanders and Alexandria Ocasio-Cortez — use “democratic socialist” as a badge of the campaign’s ambitions: proof, in their telling, that redistributive policy can win citywide. They point to the 2025 results (50.78% in a three-way general, certified) as the evidence.
How critics use the term
Critics use the same label as a warning. During the 2025 campaign, opponents — including Andrew Cuomo’s campaign and President Donald Trump, who called Mamdani a “100% Communist Lunatic” on social media — framed democratic socialism as a threat to the city’s economy and public safety. The American Jewish Committee and other critics have tied the label to Mamdani’s positions on Israel, arguing that his worldview is hostile to Jewish New Yorkers. These are the critics’ characterizations, presented as theirs.
The site’s position
This site does not adjudicate the ideology. It quotes Mamdani’s own definition verbatim, attributes supporters’ and critics’ framings to them, and tracks what the label has produced in policy terms on Public Record. Evaluative claims about socialism — good or bad — belong to their authors.
