A book excerpt posted today on Salon.com takes a look at the political wrangling during the days following Hurricane Katrina in New Orleans. The excerpt is from Paul Alexander's forthcoming book Machiavelli's Shadow: The Rise and Fall of Karl Rove. Relying heavily on interviews with former Gov. Kathleen Blanco and Sen. Mary Landrieu, the account details the back-and-forth between Blanco's administration, New Orleans Mayor Ray Nagin and the White House. Read "How Karl Rove played politics while people drowned."
