I think it's very unlikely that Wilson was the one who leaked to Novak, but it's quite possible that he himself "outed" his wife at some earlier point in time, and that this entered into the gossip pipeline and was indirectly the source of the information that eventually got to Novak. Wilson is a yakker, and I wouldn't be surprised if he was the one who originally divulged his wife's CIA connection to someone.

that would actually work out better, if Wilson outed his wife to some Dem politician - and that politician is the source. I can only dream it was Biden.

My bet is on Wilson because he is a show-off, and shallow, and needed credibility. He made his flimsy yellow-cake story and was criticized for having spent only one week, in a hotel lobby or something, talking to some Nigerians, and not making a thorough investigation.

When confronted with the lack of credibility of his story, I think he probably backed it up by saying something like "I have other sources also -- my wife, who is a CIA agent specializing in WMD".
