They think Rove is the brains behind GW's two Presidential elections, so they have to discredit him. Destroy him so he can't make a living in politics. This is right out of the Liberal play manual, and every time republicans cave in to these tactics, it increases the likelihood someone else will be targeted. Positive reinforcement works with dogs, too.
I'm not sure, but I don't think President Bush can run again. The dummies are treating every situation as if Pres. Bush is going to run against their candidate! Somebody please tell them this is his last term.
