Many Pennsylvania delegates say they will vote for the winner of their Congressional district, so a large win in PA could easily net Trump half of those delegates (if they keep their word).
Here’s my question about those PA unpledged delegates: Sure, a large number of the delegate candidates there have said that they’ll vote with their district, but doesn’t Cruz also have a number of his own delegate candidates there? If Cruz’s organizational prowess is really good there, might he not be able to get his people elected even in districts where he’s doing badly, if the Trump people are so disorganized that they can’t get their voters to back the “right” candidates?
