Cruz is highly intelligent, calm, personable. I think he is not capable of saying anything nonsensical.
I presume you are being sarcastic. Calm is not a word I would use for Cruz. I do agree he has impressed me as intelligent. Maybe Cruz was misquoted in the reported regarding the tirade he had about the KKK. I did not hear it myself. But I have heard him make accusations against Trump that were nonsenses. His association with Beck stupid. His attacks on Trump will not win over Trump supporters. He should be promoting himself, telling us how he plans to stop the invasion of this country and ISIS infiltration.
