Doubt there's going to be a real outpouring of support of non White voters for her in NYC, as they've been royally fukked by Cuomo and other establishment leaders, a few of whom are on corruption charges. Others aren't feeling the token Hillary appearances, and she didn't go hard for Bill de Blasio either. He's still very popular amongst non White voters, but the enthusiasm, overall, is very down.
The big if is if non White voters will vote, as they have jobs that they HAVE to keep, because expenses are INSANE. If they do, they would likely go for the candidate promising higher wages as 8.5 with no welfare subsidies, unless you have expensive children, is insane. The wave in NYC, as he will attract the hipster generation and people falling quickly behind, favors Sanders. She has to articulate, and quickly, why very slow change somehow favors them and their children. They've lived through Obama and Cuomo, and from what I've seen, are even hungrier, as everyone they're/we're in the subways with at rush hour looks like they're eating.
They're not voting Hillary

. The Battle for New York is on.
