As Digby says:
[Republicans] are making a mistake by pounding the fact that the entire leadership of the Democratic party including Kerry and Clinton are calling for Rove to resign. Mehlman even seemed a little gobsmacked by it. The problem is that almost everybody in the country believes that Democrats are the last people on the planet to go out on a limb. Without realizing it, Mehlman is being hoist by his own petard. Somebody just turned to me and said, "Jesus, if they're saying it, he must be toast."
Calling Democrats wimps for 20 years has its effects. It means that when they actually do say something people automatically assume that they aren't acting out of political courage. They assume that there is no risk involved.
Mehlman also said that everyone knows that Karl Rove has the highest ethical standards. Hahahahahaha. To quote the Clenis --- that dog won't hunt. Once again, they are hoist by their own petard. You can't go around telling everyone who'll listen that Karl Rove is a cross between Sun Tzu and Machiavelli for years on end and then suddenly portray him as a simple, straight shooting public servant. Only the most ardent neanderthals are going to buy this. Certainly not one member of the press will.
As Digby's post continues, Bush's ratings for being "honest and trustworthy" have now sunk to a new low of 41%. The effort to backpedal from the party line is only going to make matters worse.
