I think there are polls in New York which show Trump ahead.
Losing New York would be a severe blow to Democraps.
Heck, even fighting for NY would be a blow.
I remember that Drudge story... those were "private" polls. If they had some measure of believability, the Trump people would've paid whomever was necessary to get that data into the public eye.
Hillary is campaigning against Trump but he isn’t campaigning against her. That all changes after he wins the nomination. Current polls are worthless.
