I don't know about this idea a friend of mine has: the papers which turned up recently indicating more AWOL behavior from Dubya during his National Guard years actually WERE forgeries... but ones approved by Karl Rove and leaked to CBS by Rove or one of his operatives. Is Rove really that devious? Some believe he has already been behind both the outing of CIA agent Valerie Plame and the Swift Boat Veterans ads. After thinking about this for a bit, I have to say it really wouldn't surprise me if Rove did something underhanded to make the president's opponents look like liars. He has been doing things like this for the past 20+ years.
I don't believe Karl Rove has an equal in the Democratic party when it comes to the Department of Dirty Tricks. As long as the GOP has Rove giving advice and setting up more sly schemes, the Republicans will always be one step ahead of the Democrats... and playing "catch-up" is not often an easy thing.
