All Biden knows how to do is criticize. When will he ever offer solutions to a problem? He did the same thing when Bush was in power. Wait til after he makes a decision, then hammer away at him.... Anyway, at least he speaks his mind.
Just to correct myself, if my memory serves me, Biden did have some concrete ideas to be implemented in Iraq that no one ever listened to. So he was one of the few that criticized with other ideas in mind as opposed to just criticizing....
