Cheney and his doc - just a rumor of replacement?

Don't you sometimes wish there was an alternate universe in which you could see events unfold, just to see if you would have gotten it right had things been different?  There's an article in today's New York Times stating this big ol' rumor in DC that Cheney dropped his doc so that he could get another one to delcare him "unfit" so that Bush could safely drop him from the ticket. Now that the rumor's out, looks like Bush is stuck with him.  Wonder if the rumor is out in the A.U.
