You do realize Cruz defeated Rubio's amnesty bill while, as Cruz says, "Trump was firing Dennis Rodman on 'The Apprentice.'" Cruz is stronger on illegal immigration than Trump (who will let "the good ones" back in). Just his stance on socialized medicine should make you RUN! You are buying into his personality and not his ideas. Sure he's an egomaniacal prick, and there is some appeal to that, but he's also dumb and that's a dangerous combination.
Trump looked like he didn't believe Cruz when Cruz said he has been talking about border security since he ran for Senate in 2011. Trump really thinks building a wall was his idea that he originated last year. He's a boob.
