New York City Mayor Zohran Mamdani said Thursday that democratic socialism is a political ideology he believes can succeed broadly, as he marked his first 100 days in office. Mamdani, who took office on January 1, framed his agenda around the view that the working class represents the majority in the United States and said policy should be designed around their interests.
In outlining early actions, Mamdani pointed to several campaign commitments he said his administration has already moved forward. He cited an expansion of free childcare programs, the creation of an Office of Community Safety, and the announcement of the site for New York City’s first city-run grocery store. He presented these steps as part of a broader effort to deliver tangible services through city government.
Other major promises remain unfinished. Mamdani said a rent freeze and free city buses are still in progress, with work continuing on both tracks. On rent policy, the city is seeking to fill vacancies on the rent-stabilized housing board, and a decision is expected this summer. On transit, the city is working with Albany on a plan to make buses free, while also accelerating bus service that the mayor said affects more than one million New Yorkers.
Mamdani also highlighted a joint effort with New York Governor Kathy Hochul focused on property taxation. He said they are pursuing a tax on secondary homes valued over $5 million that are owned by non-New Yorkers, a measure projected to raise $500 million for the city. Mamdani described the proposal as part of an attempt to make the city’s tax structure fairer, positioning it as a revenue tool tied to high-value assets rather than broader-based increases.
On national politics, Mamdani said he has continued communicating with former President Trump despite political differences. He described a shared affection for New York City as a point of agreement, while not suggesting broader alignment beyond that stated common ground.
Public opinion data offered a mixed snapshot as Mamdani approached the 100-day milestone. A Marist poll put his approval rating at 48%, with 30% disapproval and 23% undecided. The figures indicate a sizable share of residents still forming an opinion, even as the administration points to early program changes and pending decisions on housing and transit.
