For anyone who thinks Howard Dean is a looney for his Iowa speech, here's some evidence to the contrary. This article at the Columbia Journalism Review points out how the media's been manufacturing the "Dean is crazy" story since Iowa.
In fact there's been a strong pattern of the media bashing Dean more than any other candidate. This Associated Press article cites a study of news stories in 2003 that found that, "49 percent of the coverage of former Vermont Gov. Dean was positive, compared to 78 percent of the rest of the Democratic field, collectively." Part of that's because Dean was the front-runner, and hence the target of negative attacks from all the other candidates. Another factor might be that Dean tends to state his opinions frankly--unlike most other candidates who deflect questions and hedge their answers more--so he gives the press more ammunition to work with.
I still think Dean's the best candidate out there. Quirky, yes, but crazy, no. He may still produce a stong showing in New Hampshire.
