It didn't take long for Barack Obama's vice presidential candidate Joe Biden to come out swinging against the general election opponent, John McCain. In his first campaign appearance today in Springfield, Ill., Biden talked about Americans having to sit at their kitchen tables and figure out where the money is going to come from. "That's not a worry John McCain has to worry about. It's a pretty hard experience. He'll have to figure out which of the seven kitchen tables to sit at."
