It will be interesting to hear Sen. Biden blasting away at John McCain, after saying in 2004 that McCain is so great that McCain should have been Kerry's running mate on the 2004 Democratic ticket: "I think John McCain would be a great candidate for vice president," Biden said.
Sure, Biden will make things interesting, but I don't see how he will really help the Democratic ticket very much. Yes, Biden has some foreign policy expertise, but let's face it: Biden is not exactly known for spotless integrity or discretion. He is known for bloviating, so in that sense he kind of complements and reenforces the presidential nominee. Plus he can probably deliver Delaware, which is a loss that Senator McCain will have to somehow cope with. Anyway, we'll now have to wait and see who McCain picks.
