If Trump really believes that Cruz could not be President due to the unconstitutional NBC, gracious or not he should not even be looking to Cruz for VP. Trump is all over the place...with everything! Also, if Cruz is the biggest liar that Trump knows (as he has stated so many times), why would he consider him for VP?
Trump always knew that his real enemies where the Bushes and Ted was just their tool. And Ted may mend his ways in the future and serve the country with honor. Trump likes fighters and Cruz fought him much longer and harder than anyone else.
