Happy Now?

We talk politics with NPR's Juan Williams--who takes the temperature of the Obama campaign--as well as Newt Gingrich, who'll also discuss his novelization of the attack on Pearl Harbor. Also: the author of The Happiness Myth on what that period of mourning after Princess Diana's death and the Gay Pride Parade have in common, taking the "Food Stamp Challenge"; and the next in our series of Anything But the Car: Pedicabs.
