Won't happen. I live and work in the New York area and travel to New England a lot as well. Here in the Northeast, easily 75% percent of Democrats under 30 years old are for Bernie and no way will they flip over to Shrillary. Not saying that Bernie will take New York but he'll definitely be well over 15%.
Shrillary has huge problems with the under 30 demographic. She's going to need the aging feminist/lesbian crowd to carry her. It may not even be enough to get her the nomination, much less the general.
You would know the NE far better than I would.
