USA Hot : Polls show Obama ahead of Romney in presidential elections

US President Barack Obama is apparently surging ahead of his Republican challenger Mitt Romney in the presidential race, as he extends a considerable lead in key battle ground states, a series of latest opinion polls have shown. But Romney campaign insists that they are not worried by these latest polls. The latest Gallup tracking and Bloomberg polls results released yesterday showed that Obama is leading over Romney by 6 points. The National Journal polls revealed Obama's lead by seven points, while the US President was leading by three points in a Politico poll. It's only the Rasmussen poll in which Obama and Romney are seen at a tie.
