U.S. stock futures rise as Americans head to the polls.

U.S. stock futures and EU shares were higher this morning (U.S. time) as Americans headed to the polls. The gains came despite the uncertainty caused by the tightness of the presidential race and the strong chance that Congress could again end up divided and deadlocked. Stocks that could apparently do well if Barack Obama wins include healthcare services, homebuilding, and food and staples retailing, although banks could sell off. "Mitt Romney stocks" include coal, specialty retail, managed care and telecommunications services
