Joe Biden, Senator of Delaware
Vaulted over the other members of the Little Three by speaking loudly, leavened by the passion he showed as a presidential candidate in 1987. Stole the thunder from Dodd on Iraq and the mantle of responsibility from Richardson. Still, however, he came across as more senatorial than presidential, more strident than forceful and delivered more high volume than sharp message. If he somehow becomes the party's nominee, he'll be able to say it began here tonight.
