Mitt Romney's debate performance has propelled him past President Barack Obama in the polls in Colorado and nationally, according to post-debate polls conducted by Gravis Marketing and Clarus Research, respectively.
Romney leads Obama by one point (47% to 46%) in the Clarus Research poll, which was conducted nationwide on Thursday. On Tuesday, before the debate, Obama led Romney by 4 points (49% to 45%) in the same poll.
In the Gravis Marketing Colorado poll, which was conducted October 3-4, Romney leads Obama by 3.5 points, 49.4% to 45.9%. In Gravis Marketing's September 25th poll of Colorado voters, Obama led Romney by 4.7 points, 50.2% to 45.5%.
Wednesday's debate was held in Denver, Colorado. Obama won Colorado by nine points in 2009, but he has been underperforming in 2008 in one of the most important swing states that could potentially flip to Romney in 2012.
