Romney’s big gain over the last month has been with white voters, who he’s going from leading 52-45 with to 55-42. He’s made gains across the party spectrum, notably increasing his crossover support with Democrats from 10% to 16% and cutting Obama’s lead with independents from 15 points down to 7 points.
The main groups fueling Obama’s continued lead are Hispanics, who give him a 67-32 advantage, and young voters who favor him 67-33.
When Gary Johnson’s included he gets 3% and actually takes mostly from Obama, pulling his lead over Romney down to 48/47. That could be something worth keeping an eye on.
