Dean is under the microscope and is a target of both the Republicans as well as establishment Democrats. The guy will not be able to fart without having it replayed and dissected and critiqued.
He did make an ass of himself but it's pretty much a non-story. The media is spending a lot of time on it because (A) it's funny and (B) they are lazy sacks who would rather write a story about John Edwards having "good hair" than John Edwards' platform.
If the Republicans are going to be allowed to choose the Democratic nominee then this country is screwed. And to me, that's what this story is all about. A whole lot of nothing. The Republicans are trying to seize on this little episode and trying to use it to paint Dean as "mean" and "crazy". That's horseshit.
If you are a Democrat or Independant, don't let Republicans tell you who your candidate should be.
Personally, I would be more happy with any of the front four Democrats as president instead of Bush. If Dean doesn't make the cut, too bad. It seems to me that the Repugs are starting to realize this election isn't going to be the cakewalk they imagined it would be, just a few weeks ago, and now they are on the attack.
