Renegade: The Making of a President (Richard Wolffe, 2009) is a chance to relive Obama's primary and general election campaigns, if you are inclined to do so. If you're not an Obama supporter, this probably isn't the book for you, since Wolffe clearly admires his subject. I didn't learn a whole lot I didn't already know, but as someone who spent the better part of a year anxiously following political blogs, taking part in my precinct and district caucuses, agonizing over swing states, and the like, it was fun to read about the campaign from the relaxed safety of knowing how it was going to end.
The one thing that surprised me a bit was how much Obama and his team were making things up as they went along. Especially by the time the primaries were over, they just seemed so smooth and so in control that I assumed they had a Master Plan. Knowing he's an improviser does make the POTUS seem more human--and given the state of the world, it's probably just as well he's good at thinking on the fly.
