I think his first attacks will sound good and score points, but his problem will be Ryan knows the facts better than Biden and his counterpunches will land and Joe won’t know what to do. That is when we will get the gaffe or crazy sound bite we are all expecting.
The only thing Biden has going for him is everyone thinks he will mess it up and the expectations for him are very low. This is Ryan’s first big debate so nobody knows what to expect from him but I bet we will get a heavy dose of gas prices, personal income and deficit talk. If Biden hits to hard it will be easy for Ryan to use some of his own comments against him.
