Trump owes Bannon bigtime in helping Trump defeat Hillary to become President of the US.  Bannon took a page from Hilter's political playbook of vilifying Jewish and destroying his competition with Trump vilifying Hillary and destroying his Republican competitors as weak and ineffective such as 'low energy Jeb, 'little Marco, etc.   Bannon had Trump instill white national pride and the promise of bringing white back into the Whitehouse after 8 years of Obama and that worked well with the US electoral college as the popular vote is now meaningless.
