You make a good point in general, but you're wrong that Bannon is in any way a conservative. He and his bunch are deeply radical and have no interest in 'conserving' anything.

Bannon is at the vanguard of a small, highly motivated movement that wants to burn down the current world order and replace it with their own take on the Third Reich, where  government of the people, for the people, by the people is replaced with government by alternative facts controlled by the Ministry of Truth. 

Trump is an intellectual lightweight. He's pathetic. His narcissism and ego have made him the pawn - maybe even the victim - of a manipulative psychopath. Trump is the Manchurian Candidate, but he's not Russia's puppet. He's controlled by the modern incarnation of the the National Socialist movement. They'll eat him alive.
