Now that would be some kind of coup, if Herself, the Cold and Joyless, could somehow entice Karl Rove to become part of her campaign, if for no other reason than to prevent any Republican from utilizing Rove’s talents.
Continuing in this highly unlikely scenario, Herself, once she is coronated - er - nominated by the DNC, declares a “Fusion ticket”, picking up one of the less well-known Republican possibilities for high office as her VP. (No, not McCain, He is cuffing CRAZY, man.) This fusion ticket would have the smug and complacent “middle” all satisfied, as if something that had been troubling them greatly had finally been “solved”.
One thing that may be counted on, however, is that the already highly polarized segments of the electorate will be totally DISSATISFIED, and may not be so very restrained about demonstrating this dissatisfaction. Cleavage of the nation becomes a very real possibility at that time.
But this is all sheer speculation. Karl Rove is not THAT self-centered.
