Pres Obama Leads in 3 Swing States

(CBS News) President Obama leads Mitt Romney among likely voters in Ohio and Florida - and has a double-digit lead in Pennsylvania - according to a Quinnipiac University/CBS News/New York Times poll released this morning.

The poll, conducted from July 24-30, shows Mr. Obama leading his presumptive Republican challenger 53 percent to 42 percent in Pennsylvania. The 11-point lead results largely from independents, who favor the president by 22 points, and women, who favor the president by 24 points.

Mr. Obama holds a six-point lead in Ohio, 50 percent to 44 percent, a state where he holds a campaign event later today. His lead here is also due in large part to women, who back him by a 21-point margin. Romney leads by ten points among Ohio men, and seven points among Ohio whites.

In Florida, Mr. Obama also holds a six point lead, 51 percent to 45 percent.
