The poll by Quinnipiac University, CBS News and the New York Times had a margin of error of 2.8 percentage points in Florida and 2.9 percentage points in Ohio and Pennsylvania.

Obama led Romney 54 percent to 42 percent in Pennsylvania, 53-43 in Ohio and 53- 44 in Florida, the biggest prize of the three key battleground states with 29 electoral votes.
