After the Wisconsin primary upset of both Democrat Hillary Clinton and Republican Donald Trump, there is a feeling that real race has finally begun. And what better place to hold the next nominating contest than in New York, where the delegate count is high, the voters diverse and the political landscape notoriously tough? Trump, a New York native, and his Republican rival Texas Sen. Ted Cruz are vying for 95 delegates. 291 Democratic delegates are up for grabs for Brooklyn native Bernie Sanders and Clinton (who made the state her home and became its senator after serving two-terms as First Lady). For both parties, winning or losing the April 19 primary could make or break a candidacy, either mathematically or invincibility. And political experts agree: New York is not a slam-dunk for any of them.
