Clinton picked the wrong guy to lie about. Roger Porter is as square and clean a guy as there is. He is a "policy wonk," not a political guy at all. I took a class from him at the Kennedy School in 1980, and knew him in the Reagan administration as well. There is no way he would ever have had a political conversation with Bill Clinton, much less use the kind of language Clinton says he did. Porter knows a lot of very influential people in both parties and is uniformly highly regarded. It was incredibly stupid of Clinton to put this fairy tale in his book, no matter how many times he may have told the story to his friends. Porter is being a lot more classy about this than most people would be.
"Incredibly stupid" and "fairy tale" seem to be terms I routinely associate with x42.
