The "alt-right" isn't exactly filled with deep-thinkers. They'll follow wherever the Breitbarts of the world lead them, so long as they're provided with someone to hate. 



It's really interesting to read the comments on TD and Breitbart. What I've seen basically goes:

Guy1: "OMG, they fired Bannon. I'm off the train"
Guy2: "No, man, this was totally the plan. He'll be more effective outside of the WH"
Guy1: "Oh, great, then I'm totally back in!"

I don't think this changed much of anything for the faithful.
