BanOn probably thought this missive would be the end of Trump.
Your story, of the fired up and comer, sounds very similar to Sloppy Steve (SS).
‘BanOn probably thought this missive would be the end of Trump.’
That is the key. The only explanation for the “grotesque,” [quoting Steve Miller] things Bannon said is that he thought the book would take Trump down. His goal was to, “burn it to the ground.”
When the plan failed, Bannon was left holding the bag. It’s the only explanation that fits all the known facts.
