Let us take a moment to appreciate the brainy political wonder that is David Plouffe. Without Plouffe and David Axelrod—if, for example, Obama gave Hillary Clinton's strategy team the reins to his campaign after the primaries—we could be living in President John McCain's America. Plouffe is reading from his campaign memoir, The Audacity to Win, tonight, and he'll be taking audience questions. It's a rare opportunity to discuss important issues—someone please bring up gay marriage in the Q&A—with a brilliant member of the president's inner circle.
