Mr. Cruz is a Harvard debate champion and, as the libs are finding out, very difficult to rattle. Ever hear Hillary as she gets excited while speaking? Her voice gets more and more shrill. You won't hear that from Mr. Cruz. If those two are running against each other in 2016, the contrast will be striking.
Cruz is a Harvard law grad graduating in the top half of his class but I think he was a debate champion at Princeton. His debate skills were born when he was still a pup in Texas.
