Is more important than staving off total economic collapse.

Oh, sure, McCain might just have flip-flopped and decided to debate tonight when he realized his gambit had failed.

But I think something else happened. I think Mississippi governor and big-time GOP lobbyist Haley Barbour made it clear to McCain that he would be rather unhappy if the debate--in which Mississippi has already invested millions--didn't go off as planned.

After all, McCain's is the campaign run by and for big-time lobbyists. McCain would rather lose a debate and crash the economy than lose the goodwill of a lobbyist like Haley Barbour.
