Take a Memo:
Supporters and endorsements don't mean jack. Delegates are all that matter. At this point, neither Trump or Cruz appears to have the magical 1237 needed to seal the deal on the first ballot. The only possible way to defeat Trump as the nominee is through a brokered convention.
On the second (and subsequent) ballots, delegates bound to Rubio, Carson, Bush, Christie, etc., can switch to Trump, Cruz or someone else. Here's where it goes wonky for the Establishment... it's never been "someone else." It has been the #2 guy... Lincoln won nomination as such. Additionally, they are bound by the rules they've established. Rule 40 is something you're going to hear about. In order to be eligible on the 2nd ballot, you have to have received a majority of delegates in at least 8 states. Cruz is now the only candidate who could meet that criteria.
