your first book, "bush on the couch" what's one thing we learned about president george w. bush? >> we learned a couple of things that he really was very much a person who had once been an alcoholic, a dry drunk, people who are impulsive and given to blaming other people and one of the things about him so powerful is that he -- when he made up his mind, he never changed it, and he's an either/or president, with us or against it. he lived in a different world saying i don't do knew answer or deal with it, and obama only does nuance so there's the opposite presidents back-to-back. . ..
