Whether the first hundred days become a foundation or a high-water mark depends partly on Albany. The budget gap Mamdani inherited from previous city and state administrations constrains new investment, and his largest revenue proposal, the wealth tax, requires the governor and state legislature to act. But the trajectory is already set. By fall, 2,000 two-year-olds will have full-day, full-year childcare seats that did not exist in January. By 2027, a city-run grocery store will open in East Harlem selling subsidized food on the same spot where LaGuardia built one ninety years ago. Those cost money the way fire departments and public schools cost money: because delivering the service is the point.
