I caught a bit of Anderson Cooper's show on CNN last night and  was fairly shocked by the degree to which the campaigns and the media's coverage already lacks any kind of substance. Perhaps the most startingly vacuous analysis came from Candy Crowley.

CANDY CROWLEY, CNN SENIOR POLITICAL CORRESPONDENT: [...] John Edwards, Barack Obama and Hillary Clinton all came back to the original theme that has gone throughout this Democratic race. And that is one of change. You know, John Edwards fighting for his life at this point, says he can change because he's the toughest. Barack Obama, he's the newest. Hillary Clinton says, listen, I'm the one with the experience. So, we're back to the original arguments.

Kay noted the other day that the environment seems to simply not be on the agenda. Another important issue we've heard barely anything about is American policy on the Israeli-Palestinian conflict. So I asked five expert-types what the media shouild be asking the candidates. Read their answers here.
