<<He's got a guy with a book deal who quotes sources who wish to remain anonymous.
<<In otherwords he has nothing, nada, zip.>>
Let's be a little more accurate, please. If I DIDN'T have a guy with a book deal, THEN I would have "nothing, nada, zip." In fact I've got Schecter, the guy with the book deal, I've ALSO got McCain NOT suing for libel despite Schecter's insistence that there were witnesses (a lawsuit would have forced Schecter to name and subpoena the witnesses, who could not claim fourth-estate privilege since the offensive words were allegedly addressed in public to Cindy, not to the journalists) and so a lawsuit which could easily resolve the truth or falsity of the allegation is for some unexplained reason avoided by McCain. The ONLY plausible reason for McCain's failure to sue is the truth of the allegations.
<<And unless we have a "Who's afraid of Virginia Wolff" scenario, where sniping is foreplay, my guess is Cindy wouldn't put up with talk like that.>>
My guess is, as a recovered addict, she'd heard a lot worse. Probably rolled off her like the proverbial water off a duck's back.
