I honestly expected more from Obama last night. He's shown that he can be a very powerful public speaker. I don't recall him looking bad in his debates against John McCain four years ago, but then again he was able to run on his hopey/changey promises for the future in 2008 instead of his track record for the previous four years. He clearly was underprepared and overmatched last night. I would expect him to bounce back and look much better for the next debate on 10/16.
If he gets publically destroyed a second time, it's going to be all over for him.
