With only six months left until the election, a new poll favors Obama in Pennsylvania, but Romney is gaining ground in Florida and Ohio. This week's Quinnipiac University poll shows that in Florida and Ohio, two key states in the presidential election, Obama and Romney are too close to call. In Pennsylvania, however, another important state, Obama is leading by 8 points (47 to 39), an increase of 5 points since the last poll in March.
