NYC has in the past pushed state laws that just affect NYC. Gun laws in particular I'm more familiar with [state preemption - except for NYC where they can enact their own gun laws], but some taxing is specially allowed for NYC too. It's not unheard of for state-level legislators (from NYC) to push for something to the state either because 1) the state constitution doesn't allow a city to do XYZ, or 2) because the city government doesn't see eye to eye with the state representatives living there
