Bruce Kluger argues — and in a way, I agree — that David Letterman is successfully handling his sex scandal via sheer candor, as opposed to certain politicians who made things worse by lying or stonewalling. True…but then again, what happens with a politician's sex scandal is that the faces of his opposition light up and say, "Ah, we can use this to our advantage!" And suddenly, he's given them a weapon by which to perhaps drive him from office or tar his party or causes or whatever. Letterman doesn't have Conan O'Brien looking to exploit this matter, nor could Conan likely gain any yardage because of it. If anything, talking about it drives viewers to Dave's show. The Mark Sanfords of the world didn't see their ratings go up.
