That's what I talked about in Part VII of my eight-segment interview with L.A. Times political blogger Andrew Malcolm (note: this was recorded before Bob Barr won the Libertarian Party nomination). Part VI was a discussion of the role of religion in McCain's life and politics. Parts I-V are linked to and described here.
Speaking of Malcolm, he has a shrewd take here (and not only because he quotes me!) about how McCain's underdog mentality has placed him right where he wants to be, at least psychologically ? hopelessly behind.
