That was one poll taken about a month ago, and no other poll agreed with it - in other words it was an outlier. He has been averaging in the low 50's over the past few weeks, about 30 points ahead. He will win the state easily, but he will not sweep all of the delegates.
Closer to 3 weeks ago in mid March that poll. Trump’s numbers can just as easily go back up in New York and it’s probably likely so. I bet Trump runs 50% plus in almost all NY CDs. Kasich may break in to get a few delegates out of NY, and Teddy, he’ll likely be shooting snake eyes.
