How Trump Can Win 1,237 Delegates

First Read explains Donald Trump’s path to the Republican nomination:

• He needs to win 90 to 95 of the 118 pledged delegates that are up for grabs in tonight’s five states;
• He needs about two-thirds of the 54 unbound delegates being elected in Pennsylvania to either be Trump supporters or folks who will support whoever wins their congressional district (i.e., Trump);
• And he needs to beat Cruz in Indiana, even if they split the delegate haul.

“If Trump accomplishes all three, his path to 1,237 will be clear. And more importantly, his opposition — Ted Cruz, John Kasich, the ‘Stop Trump’ movement — will collapse. If Cruz loses in Indiana, it’s over for him; it’s that simple. But if Trump falls short on either of those three goals, then his opposition has a rationale to keep fighting, and his path to 1,237 is more perilous.”
