I know I said Joe Biden was dead to me after the odious Bankruptcy Bill of 2005, but I can't help but feeling that the Obama campaign—and Democrats in general—need someone willing to throw a freaking punch.
Evan Bayh? Screw that. If we're going with a Senator that voted for the Iraq War, he better bring more to the table than Bayh. Joe Biden has a fastball, and he ain't afraid to throw it.
UPDATE: Kevin Drum concurs. (See, Toast?)
