Zohran Mamdani, the new democratic socialist mayor of New York City, has been in office for 100 days. In that time, he has focused on reducing the cost of living for residents through initiatives like city-run grocery stores, rent freezes, and expanded childcare. Meanwhile, former President Trump's national economic agenda of tariffs, deregulation, and immigration crackdowns failed to deliver on promises of job growth and wage increases during his first 100 days in office.

Why it matters

As the antithesis to Trump's nationalist populism, Mamdani's progressive policies in New York provide an interesting counterpoint to evaluate the real-world impacts of vastly different economic approaches at the local and national levels. The outcomes in the first 100 days offer insights into the priorities and efficacy of each leader's vision.

The details

In his first 100 days, Mayor Mamdani has pursued a slate of cost-of-living initiatives, including launching the city's first municipal grocery store in East Harlem to reduce food prices, implementing a rent freeze, and proposing $23 billion in tax increases on the wealthy to fund new social programs. He has also required all city departments to appoint 'Chief Savings Officers' to find efficiencies. Meanwhile, former President Trump's national agenda focused on trade, tariffs, and immigration restrictions, including imposing large tariffs globally, expanding fossil fuel production, and cracking down on immigration. However, this led to a GDP contraction, increased market volatility, and the failure of his DOGE initiative to reduce government waste.

  • Mamdani was sworn in as mayor of New York City on January 1, 2026.
  • Trump's first 100 days in office were in early 2025.

The takeaway
