Some interesting stats I got from a poster over on dKos (haven't confirmed them yet):
Clinton Q3 to Q4 1995: down 36%.
Gore Q3 to Q4 1999: down 44.5%.
Dean Q3 to Q4 2003: up 2% (and not done yet).
So if anyone says that Dean is stalling because he just barely managed to beat his Q3 numbers be prepared to smack them across the face with these stats.
