A survey on Wednesday raised eyebrows by giving President Barack Obama a commanding 13-point lead over his Republican rival Mitt Romney. This has occured after weeks of national polls showing the U.S. presidential race as a near dead heat. "Do I think we have a 13-point lead? No," one campaign official told reporters at a briefing in Washington. Obama's team anticipates the race will be close because the country is closely split between Democrats and Republicans.
