The sound of one hand clapping

Senator Joe Biden is running for president of the United States. Don't get too excited. Will he ever stop talking about himself? He was the low light - well, one of them - of the confirmation hearings of Samuel Alito for Supreme Court. HIs knowledge of international affairs is nearing disappearing, but he considers himself to be an expert. He will raise a lot of dust - if he can. And give the Republicans some room.
