Steve, I'm not worried about Cruz's ability to win the election. He was regarded as a sure loser when he ran for the Senate; he had almost zero name recognition, and he was going up against a popular, wealthy, self-funded candidate. Yet he won, and handily.
Cruz's ability to connect with people is very much underrated. He can go in depth with college students about the Constitution, and switch gears to discuss video games. He has a gift for persuasion, which translates into "selling" conservatism to folks who don't understand its value.
I agree that Cruz is far more affable than the MSM give him credit for, which is why the MSM are trying to poison public perceptions of him before they have a chance to hear and see him for themselves.
I think Trump is still behind the learning curve. That does not mean he should not be president this time around, but it does mean that when it comes to constitutional law and other such matters, he should defer to someone like Mark Levin or Rush — they both have a sound understanding of constitutional law.
He does not even have to state publicly if he puts them on his phone list. And rather than jump out there with kneejerk responses [which are fine when retorting to media toadies, etc], Trump should take constitutional law as the most serious topic on earth.
