I think that, ultimately, Bannon is controlled opposition. But given that, an asset is pushed to tossing around the "T"-word, which I don't think is done lightly. Theoretically you can get hanged by the neck until dead for that kind of activity.

Thus I conclude that TPTB are under extreme pressure to keep their controlled opposition out in front of the masses, because it is only from out in front that one may divert them.
