Book excerpt: From 2007 to 2010 Swaim worked for Mark Sanford, South Carolina's governor, as a communications officer and speechwriter. Everyone knows this kind of politician: a charismatic maverick who goes up against the system and its ways, but thinks he doesn't have to live by the rules. Swaim tells the story of a band of believers who attach themselves to this sort of ambitious narcissist-- and what happens when it all comes crashing down.
