Hillary?
I've long believed that Q is either Rogers or Bannon. (Maybe both together)
Bannon always struck me as a good story teller–i.e. he understands how to connect with people– and I think he has the mind for it. (Plus he understood that winning the election was only the start of the war.)
And I never bought the "fallout" between him and Trump. You don't fight back to back against the greatest evil the world has ever known, defeat them in front of the world, and then turn on each other. That seemed very calculated, to get Bannon out of the White House and away from scrutiny/prying eyes.
