Some other facts:
1. The only people frothing at the mouth because of this story were those who had a sincere dislike of Karl Rove long before any "revelations" came out. In other words, this story will end up having less effect on D.C. politics than the Nationals trading for Jose Guillen last winter.
2. The more information that comes out of this story, the more it seems that Rove did not break the law. In mentioning how Wilson got his gig in Niger, he did 'blow' Plame's cover (at least to one person) but that cover was pretty flimsy as is - to the point where reporters were contacting Rove and telling him about it.
3. If Plame's cover was so important, she wouldn't have risked it by greasing the wheels to send her husband on a trip to Niger that he would later lie about several times - about what he found, what he reported, and who sent him. When you have your "covert" CIA wife pulling strings for you, it's probably best not to perpetuate lies about the sitting POTUS in national newspapers because, believe it or not, other people will be interested in finding out a little more about you and how you got the job you lied about.
4. Joe Wilson is an extremely disingenuous person at best and a pathetic partisan hack at worst.
