Nah, can't see it happening. Trump basically showed everyone where he's leaning towards ideologically. Bannon shares Trumps worldview. If anyone is going it will be McMaster and Kelly. And all the better really, it would be worrisome if Trump was tempered by the "moderates" in the WH to the point where Republicans, Fox and the rest of the insufferable punditry declared he was now "presidential" and the fickle public would accept it as his poll numbers improve.
Everything and anything that makes Trump look like a giant walking ulcer is a good thing. We don't want this presidency to suceed so civil war within this administration and the GOP is to be encouraged.
