For more on that point specifically, lets bring in abc news chief anchor george stephanopoulos, getting ready to host this week. Hey, dan. As mary mentioned, the New York Times is reporting antitrump republicans are going launch a 100day campaign. Trying to deny him the nomination. What are the odds of success . Somebody has to beat him on the field. It will take ted cruz or john kasich to do that. You have to look at the math going forward. Coming up on tuesday, utah and donald trump is likely to win arizona. You need most likely ted cruz to beat him in utah. Hes ahead right now. But then, the big date on the calendar is april 5th. Votes. Wisconsin, a big mid western state. If the stop trump forces have any hope, they have to beat donald trump in wisconsin, on april 5th. If they do, the chances that donald trump can get those 1237 delegates before the convention go down dramatically. And perhaps, after april 5th, it would be a twoperson race. That would give the antitrump forces a better shot. Thats the key day. What theyre saying, the reports are saying that the antitrump folks, if they cant deny him the nomination, they may support a third party candidate. Wouldnt that throw the election to Hillary Clinton . Most likely. Yes. It could throw to it the house. Most likely, it would throw the election to Hillary Clinton.
