I think this David Brooks column on Steve Bannon and the different ideologies fighting for Trump's tiny attention span sounds as if it is accurate. But he ends by saying that he thinks even as Bannon fails with Trump, he may have more influence on the next generation.
I have my doubts about that. For one thing, Bannon is a remarkably unhealthy looking 63 year old - the puffy face and general tired look just doesn't suggest to me someone whose health is going to hold up long. And besides, isn't he just a bit of an opportunist who has floated from career to career? I think he'll fall out with Trump - assuming Trump makes it to the inauguration - soon enough and we won't hear much of him again.
