RE: Cruz is acceptable to the GOPe, Trump is not.
Actually, BOTH are hated by the GOPe. It can in fact be argued that Trump would be more acceptable.
I do believe the GOPe hates Cruz more than Trump. Cruz is a hardline conservative. They hate conservatism. They hate his record in the Senate. They hate his fan base. GOPe only wants our continued servitude to them so they can retain power.
I think the GOPe might find Trump more acceptable however the uniparty would be happier with Cruz. Cruz's agenda would be bead on arrival if he is elected president. Cruz has not displayed any ability to work with others to accomplish anything. He is disliked by just about everyone in DC. So with Cruz we get a continuation of the status quo, which is fine with the uniparty.
Trump however might be able to get his a good part of his agenda thru Congress. He has a history of success and his genuinely liked by just about everyone he does business with. He knows how to play hardball and win. And someof Trumps' ideas are (tax reform) liked by the GOPe.
Ergo I think you are correct about Trump, he would be preferred by the GOPe but not preferred by the uniparty.
While I often equate the uniparty with the GOPe they are not identical. Just like Cruz has adopted most of Trump agenda Cruz and Trump are not identical either. Of the two I place more trust in Trump to actually do what he says he would do if elected. Cruz just flip flops do much for me to trust him.
