That much has been pretty well CONCLUSIVELY demonstrated by numerous commentators, former colleagues, and other members of the Bushit Cabal, and the fucknozzle himself.
What needs to happen next is that Karl Rove get the lying shit beaten out of him. Some body needs to corner the twisted little twerp and open up a six-pack of Kick-Ass all over his pudgy butt. He needs to be beaten til his knees collapse and he shits himself while crawling away, weeping in his shame and humiliation.
I am, of course, not advocating such a thing; i would NEVER call for harm to befall a fellow human being, particularly a (former) public official. I am merely remarking: cosmically, karmically, it needs to happen. Some balance needs to be restored. Karl Rove sobbing piteously in his shit-sodden pants would be a good first step.
