Bill, I was unaware there was an urban legend that the leaking had been an official Senate act. Congratulations, you got me. But the later urban legend doesn't change the facts as they initially happened.
Part of the attacks on Bork were the printing of his video rental history by a newspaper. The attacks on Kagan you and Matt were talking about were criticisms of her personal life printed in a newspaper. Yes, the part of the confirmation process that takes place in the Senate chamber may have changed, but the fact that aspects of a nominee's private life irrelevant to their legal philosophy are part of the public debate is nothing new.
