Bannon is not a stupid man, nor does he lack ambition. He may very well reason that America would be better off in the long term if establishment Republicans are replaced by Democrats. At the very least, this outcome would be a small price to pay for revolution. It might even be part of the plan. Anyone who is keen on toppling the institutions of the state shouldn’t fret too much about ousting a silly little political party from power.
This is what you would expect of a man who wants “to bring everything crashing down, and destroy all of today’s establishment.”
It’s almost as if Steve Bannon is trying to cost Republicans seats in next year’s midterm elections.
