Trump’s lack of preparation should give his supporters cause for concern. Cruz is far better organized. And smarter and more articulate... I could go on.
So YOU ARE PROUD to be supporting a professional politician, WE on the other hand are PROUD to be supporting a TRUE outsider READY to blow up DC!!! You feel your guy is SO smart, our guy is just now learning how corrupt politics can be, your guy IS the corruption he is fighting!!!
Cruz was not better prepared after losing the south so badly. But the GOPe was with most of the delegates lined up from the party insiders. It boggles the mind why Cruz supporters attribute to Cruz what the GOPe did after they came in. They only needed to claim being for Cruz to stop Trump. However that would not explain why the GOPe is so sure Paul Ryan or another Rino is getting it.
The simpilist explanation is usually the right one. Cruz used the existing GOPe system - he did not create a new one from the shambles of his southern loss.
