Gregory seemed to get exercised the most but there was enough frustration to go around.
Two things are apparent to me: 1) No one has all the facts yet and 2) If Rove was 'getable,' the left side of the media would have already gotten him.
I actually think that the important thing is Plame's interference in the activities of the CIA in order to get her husband (unemployed) a trip with expences covered, a trip whose findings he LIED about for partisan purposes.
This whole thing has been fishy from the get-go. If Rove wanted to retaliate against Wilson, there were far better ways to do so, none of which involved Plame.
