We can't succumb to using the right's definition of what a "left-wing extremist" is --- I mean, what they don't get is that 'liberal' and 'extremist' are not the same thing.  I mean, really.  We need to be putting some concerted effort into informing people how mainstream the Democratic party is and how far to the right the Republican theo/neocon leadership has taken theirs.

Dean is not extreme.  He's just very committed to his principles.
