Wow.
Bannon by himself is nothing. He is not a leader. He is not an ideologue. He is singular organism that must live off another. Like the Costa Rican parasitic wasp, Bannon attaches himself to a host, poisons it to gain control over it and builds a home from within while the host ultimately dies off.
It is a pattern we have seen from Bannon time and again. From Palin to Paul, Cruz to Carson, Trump to perhaps Le Pen, the story always ends the same way: the host loses everything and Steve searches for a new home.
