Constitutional Crisis?

Given current state polls, a not so unlikely scenario seems to be upon us. What if Bush holds the same states he won except for Florida and New Hampshire and adds Wisconsin, Iowa and New Mexico (not only is this not unlikely, but, most agree the t three states Bush has the best chance of picking up are those while two of the three for Kerry are the ones Bush loses)? The result is a 269-269 tie. The election gets thrown to the house then, where it would seem compromise would be unlikely (as far as I can tell there are at least two different constitutional readings here, both would create chaos). The answer then might be not Kerry or Bush, but, bringing in another compromise ticket, i.e. McCain-Breaux or McCain-Graham. Not all too likely, but if I told you a week ago that the Red Sox would come back from three games down and a game three thrashing to win the series, you would laughed just as hard.
