I don’t presume to know which side he favors. Given that he fired his own brother for failing to perform, I don’t think you should draw those conclusions either.
And BTW, his widely reported Washington Examiner comment would apply to Kush, Conway, and Miller. Trump won the primary without any of them.
He won’t fire Kushner until Kushner has a dramatic fall.
So either Bannon has to kowtow to Kushner until that happens -thus Trump’s very public kick in the gonads to Bannon - or he will be relegated to another position or pushed out.
The only people that can save Bannon other than himself are the Mercers..
