obama finds the perfect role for joe biden

"No doubt, Obama figured: It doesn't matter what he has to say, so long as he keeps talking long enough for the press to get its photo-op without Crowley tasing Gates or Gates flipping over the table to shout, "Do you know who I am?" Biden could just simply switch on his mouth's autopilot and jibber-jabber about Iraqi Kurds, socket wrenches, gay basset hounds, Social Security, World War II, World War II-and-a-Half, World War II-and-Three-Quarters and whatever else popped into his mind. Anything to eat up the time would do. This theory's appeal lies in that it's very hard to figure out what Joe Biden is doing in the Obama administration in the first place, especially since every time he lends the benefit of his experience and insight, the White House corrects him."
