I'm going to go out on a limb and assume that Trump, considering he wants to win in everything he does, will shore up the part of the vote that is not only important this year, but also 4 years from now (the hispanic vote), and ask Rubio to be his VP candidate. My second guess is Kasaic. They each come from states which figure prominently in the delegates count. Choosing Rubio is the one way he can make peace with the establishment without truly giving in.

All of the anger back and forth between the two? No different than the barely contained contempt Hillary shows for Sanders. It's all water under the bridge when it comes to the general election.

Christie is an attorney general pick, and not more. I think Trump would see that Christie as VP would be a drag on his momentum, and he did not need Christie's endorsement that bad.
