This is the third biography of James Madison that I've read but it's the first that was more than 200 pages in length. I suspect this is why I'm getting so much more out of this one, as I usually retain more from longer books (which is a major reason why I prefer them, despite the greater reading commitment involved) and Madison is someone the details of who's life I have wanted to master for a long time now. And Ketcham's book has details aplenty -- and not trivia, but analysis of his thinking. It's deepened my appreciation of his ideas and his motivations, which will undoubtedly help me better cover him the next time I teach the first half of the U.S. history survey.
