No, I believe that Romney will prevail and I believe the state polls will soon reflect national polls which give Romney the lead. The reason for this is because in the week before the elections, the pollsters reputations are on the line and they don't want to be wrong! This is just a guess on my part as I agree with Attikos, that nobody really knows at this point!
I believe another 4 years of Obama may harm the country for a generation or more. The national debt is reaching levels of the failed European countries. He believes he can tax and spend his way to an economic recovery. Even though his policies have flatlined the economy, he shows no signs of changing course.
Worldwide Obama has projected America as weak and declining, which is usually a self-fulfilling prophecy! Obama is the first President to deny America's Christian roots while declaring on foreign soil that America is one of the world's largest Muslim nations. He also apologized to other world leaders for America, I don't remember any other president doing this.
