Joe Biden knows a lot about the world and foreign policy, but his instincts are frankly cruddy: he wanted a nuclear freeze during the Cold War, voted against Gulf War I, agitated to have Iraq broken up into parts (without the consent of the Iraqis), etc. Then there’s his history of playing fast and loose with the truth and putting his foot in his mouth.

The only good thing about having him as VP is that he may provide some comic relief with his inevitable windbag emissions and gaffes. One thing I have no doubt of – Biden will never have the kind of credibility with Obama that Cheney had with President George W. Bush.
