Why is it silly?
Under Clinton we had to talk to our kids about oral sex (or hide them from it). We also had to explain why the president is a liar.
If Kerry wins we get to explain why it's not OK to cheat on tests even if the president does it. I know I cheated a time or two in junior high, but if I knew that the President was a cheat, I'd probably never had stopped. Or if I got caught, my retort was so what the President cheats. I just don't want to go there.
First we need to prove he did cheat. From any of the videos I have seen on the Internet, it is not clear at all.
GW and his camp will come out way worse if it concludes Kerry didn't cheat at all and yet the GOP was looking for reasons for why GW lost (because that is how it will be spun).
Because if GW did great at the debate, no one would have cared if Kerry brought some info card - The story will be spun that the GOP is looking for reasons GW did so poorly and they will say suggesting Kerry cheated (if it turns out he didn't) is the proof the GW did lose the debate.
