Bob Novak explains the Dean phenomenon and sees more hope for Dean than some experts.

But how to stop him from being nominated? Former Clinton (and current) Lieberman pollster Mark Penn predicts Dean would lose 49 of 50 states to Bush, while a former Clinton colleague (unwilling to be quoted by name) told me: "Mark is wrong. Dean would only lose 40 states." This "he can't win" argument did not stop Barry Goldwater, George McGovern, Ronald Reagan or Jimmy Carter from being nominated, and the last two actually were elected. The party faithful liked the purity of those candidates and did not care about electability, and the same might be proved true of the Anti-Bush.
