The question on Trump is whether he is a clown or a showman. The difference is subtle but important. A clown is not worth electing. A showman who gets free publicity but also knows what he is doing might become a formidable general election candidate.
I don't think he has a single clue about what he should do if he got elected. He has no ideological core, beyond his unerring belief in the awesomeness of Trump.
I don't know where he goes with that sort of focus - but the ideological wing of the Democratic Party will promise him shiney things and he'll go along, because why shouldn't he go along with the Democrats to get things done. He has no ideological differences with them, other than he wants to build a wall and they don't. They'll concede that point, let him build a wall, while they get concessions from him on how the immigrants can all get here legally.
And Obamacare is very confusing so he'll just go to single payer, and the Dems will convince him that he's getting a great deal because it will mean no more Obamacare. And his worshippers will also think he won that one.
What's important is that he makes deals and gets things done. Stupid things, rotten things, harmful things - doesn't matter.
He's a deal maker. Best since Bob Dole, I'm guessing.
