Golly, it seems that McCain's webmasters never bothered to take down the Mississippi debate page from their web site.
Maybe....just maybe, this stunt was designed to trap Obama into accepting a debate postponement, and then calling him for being a follower, not a leader?
I don't think McCain ever meant to skip the debate at all. This was a bad attempt at a trap.
And if McCain somehow does not show-up to the debate, then oh my god, he is really stupid.
