Query: Good book for non americans to understand inside poltics

I think this book gives foreigners a great opportunity to understand the insides of American politics and the system and environment in which American President's evolve since the Watergate scandal. Bob Woodward is clearly an insider in the game of Washington politics and put into words a complex web of half truths, lies and the inner works of the American system.
