What will happen to the world's economy if Obama or McCain wins?

With a rational President in the White House (Barack Obama) we may actually be able to restore our economy to the way it was prior to Bush Jr's stint in office. Perhaps obliterate the debt accrued by 8 years of irrational and hastily made decisions. With McCain, it's hard to tell. We all hope that the same would happen but staying in this war, which will happen if McCain is elected, will keep driving us further into national debt and will continue our reputation as the a**holes of the World.
