Trump has called Romney a loser at least 1,000 times. Mitt is a bit miffed. LOL.
It's good that Palin is disparaging of Ryan's record and character.
You are certainly correct. At the same time, several prominent R's. and those they control or influence are on the verge of betraying the candidate's oath to support the nominee.
My money says Trump is not arriving at this potentially hostile conference with the weaker of two hands (or he would not be walking in).
