Right now most pundits, gamblers and general mass are betting Obama will win on Tuesday. National polls show Obama has 0.3% lead on average. State polls show Obama has significant lead. However, some recent development in leaning-obama states indicates Romney could win by surprice - even without carrying Ohio.
MN was considered a lock-in for Obama. But recent polls show dead-even. This a wild-card state where it elected a governor from a former pro-wrestling player without creditable government experience. From recent polls, MI, WI and even PA could also be candidates for Tuesday surprise.
