Cruz spoke about policy and specifics on policies and spoke about The Constitution. I think that overall, that Cruz got a much more enthusiastic response from the crowd than did Trump.
Trump started out with great applause but as he talked more and the more he talked about “him” – Trump – Trump – Trump, “Me”, “Me”, “Me”, about how “popular” he is, the polls, how the system is rigged against HIM… “lying Ted”, talking about Kasich’s eating habits, rather than speaking on any of the issues, (did he talk about any?) and he barely mentioned Hillary – the crowd and their enthusiasm, at least IMO seemed to trail off. He did get laughs and applause mind you, but so do most comedians.
