Then why is the establishment piling upon him?
If he’s good as you say for the brand, they have nothing to worry about.
By all lights, they should be welcoming, not dreading - a Reality TV presidency.
First of all, I don't think they are. We have only Trump's word that Priebus is against him. Of course, opposing candidates will attack him, but that's to be expected. Most of the GOPe is hands off. And to a degree, he wants to be criticized like that. And of course, they are going to diavow him from some of the more gauche things he says. I'm sure they don't like his style, but they love his substance. If you pay attention, the media is doing exactly what Trump wants. They only criticize him for the things he wants to be criticized for and they don't vet him at all.
