Trump presidential campaign was floundering in GE, he had been firing one campaign manager after another. Until he brought in Steve Bannon, who quit his job at Breitbart. Who knows what would happen in Nov if this move didn't happen.
Now that Trump is potus, he's surrounded by your regular swamp creatures who all want him move to their camp and pov. So the Deplorables are comfortable with compromises and dealing and wheeling on the Capitol Hill?
We will see how strong Trump resolve is, and if he forgets his singular campaign promise about illegal immigrants.
How soon they forget. Steve Bannon was key to Trump winning. So was Paul Manafort. Bannon is a free wheeling guy and was miserable in the White House. You could see that he hated putting on a suit and tie each day.
Like it or not his Presidency depends on how he handles this issue. I am not optimistic about a resolution of DACA that will firm up his base.
