I have said on this site that I will vote for Trump if he wins the nomination. But any Trump supporters that refuse to have legitimate concerns about him -- even if they ultimately vote for himn -- are not worth listening to about anything.
Vote for him if you want, but do it with your eyes open.
As for Cruz, whether or not you think he is a good presidential candidate, if you think he doesn't know more about the Constitution than you do, then you obviously haven't looked at his actual resume, which makes you just an LIV.
The devil knows a lot about the Bible too. He quoted Scripture fluently. No, I’m not comparing Cruz to the devil. I’m merely pointing out that head knowledge is worthless unless it translates into real life actions.
