As Mamdani marks his first 100 days in office, he has a mixed record on his most ambitious campaign promises as he navigates the city’s budget negotiations. While his administration has made significant headway in securing state funding to expand universal child care, other progressive centerpieces, such as free city buses and higher taxes on the wealthiest New Yorkers, have stalled due to pushback from Governor Kathy Hochul. The mayor has also been forced to scale back or reconsider several costly initiatives, like shrinking his proposed Department of Community Safety into a smaller mayoral office and reversing his previous support for expanding the CityFHEPS rental assistance program. However, he remains positioned to potentially fulfill his pledge to freeze rent on stabilized apartments after appointing pro-tenant members to the Rent Guidelines Board ahead of their upcoming vote this spring. His proposal to open city-owned grocery stores remains in play, with the administration currently scouting locations and requesting $70 million in capital funding. Ultimately, the mayor’s first 100 days highlight that the battle with Governor Hochul’s re-election rhetoric about no higher tax rates on corporations and the wealthy, and opposition from Democrats who supported former Governor Andrew Cuomo’s bid for mayor, will play a big role going forward. If even part of his plan for higher taxes passes, he could achieve many of these goals, but that may need to happen in a non-election year and will require support from the state legislature.
