It won't matter. All the stories will be about how much better Obama did this time around. When GWB showed up clueless for his first debate with Kerry, the media killed him, and rightfully so. When they had the second debate (also Town Hall format) he was much more animated. All the stories were about how much better Bush did. Nothing about substance or what he actually said - it was all about how Bush showed up this time.
This may be a hard concept for many of you to grasp; but it's like when you go on a first date with a girl, you never show up with candy and roses and jewelry. Then you have no where to go from there - you've set the bar too high. What you do is show up at her house, throw your jacket on the floor, turn on Spike TV, tell her to get you a beer and then fall asleep on her couch around 9:30. Then on the second date, you take her out for pizza and a movie and she'll think you're the greatest guy in the world.
Look, I can go on; but I won't. Just check out all the talking heads around 10PM tonight and see what they're all saying. Then you'll know candrew was right.....again.
