Slamming Hillary Clinton for crying didn't help John Edwards any in New Hampshire. In fact, it probably hurt him substantially. What makes the Obama folks think questioning those tears' authenticity will do anything other than cause a backlash?
Really? We're supposed to think that because Hillary Clinton didn't cry publicly over Katrina, these tears were part of a political calculation? This is stupid and weak.
Is assuming the worst on the behalf of your opponents part of the politics of hope?
