Romney crushed him. It was fairly obvious. Facts, body-language, fluidity of speech,....etc. He was superior throughout the debate. Romney now has some 'momentum' for the first time in a while..... with even MSM acknowledging his performance.
I think Joe Biden woke up with a huge knot in his stomach this morning. If Ryan can put on a Romney like performance (or if Biden simply is Biden) then the pendulum will have seriously swung in the direction of the challengers.
