I would not let CBS moderate any debate. I can imagine the questioning.
Schaeffer to the President: "Bush", CBS has a solid source that writes that you used cocaine you bought from you wife with your gay boyfriend, Bush, what is your reaction to this?
Scaeffer to Kerry: Esteemed Senator Kerry, to be fair and balanced I'll ask you the same question, CBS has a solid source that writes that BUSH used cocaine HE bought from HIS wife with HIS gay boyfriend, what is your reaction to this?
Please, why even bother doing a debate that CBS in isnolved in.
Give the public a little credit (although I admit it's hard) -- the scenario you fear will only appeal to the rabid foaming-at-the-mouth Dumbocrats whose vote is not in play. The voters the GOP needs to win will be tipped to our side by the attacks -- and the more outrageous they become, the better.
