There needs to be a split. I would say the boundary would be at Orange and Dutchess Counties.
I don’t know where that is. So I ask; what do you do with the pit of corruption known as Albany? (I sometimes listen to AM 810 WGY) and thay call Albany MUCH worse.)
Coumo and his ilk are from downstate. It would use most of the liberals back to the New York Metro area.
Orange and Dutchess County can be considered to be the northern edge of the New York metro. Still, upstate will have to suffer with Albany, Ithaca (The City of Evil), etc.
