New York is the 4th largest state by population in the US. New Jersey, which just legalized, right next door, is 11th. The 13th, Massachusetts, also shares a border with NY. Vermont, while not large and ranked 49th, is a legal state and boarders NY.
New York would be incomprehensibly stupid to not legalize this year, and let two fairly large states and another small one vacuum away money from them.
