What’s the Political Calculus?

Tyler Whitley of the Richmond Times-Dispatch informs that Tim Kaine will be debating Russ Potts twice next month, including an event after Kaine debates Jerry Kilgore in front of the Fairfax Chamber of Commerce.

I’m fascinated by the political calculations being made by the Kaine campaign.

Is this a mutually beneficial plan by the two candidates to rough up Kilgore? Rumors of collusion between Kaine and Potts have always been below the surface.

Has Kaine concluded that he must raise Potts’ profile and get him into the televised debate because Potts drains votes from Kilgore?

Or, has Kaine decided that he has to take Potts out now because a surge by Potts will come from Kaine’s column?

Any and all speculation or inside information in the comments will be welcomed.

Updates: Commonwealth Conservative has some theories on the Kaine-Potts debate. Norm reviews the issue and this BR discussion. Poli Amateur smells a “gentleman’s agreement” between Kaine and Potts.
