If Bannon wants to continue his revolution, he must replace Republicans in congress with Trump yes men. If Trump wants to gain a 2nd term without any legislative successes, Trump needs to play the role of victim to congressional obstruction. Perhaps Bannon can be far more effective outside the white house than inside. If Murdoch JR takes Fox news out of the looney zone, Bannon can and probably will set up a network that continues the narrative.
A 2nd Trump term could happen. The democrats have real trouble formulating a positive narrative and find themselves binge watching Trump TV 24/7 (like many of us are, getting addicted to this revolting trash).
