In Ohio, the two new live interviewer surveys both give Obama wide leads. The CBS/Times/Quinnipiac poll shows him leading by 10 percentage points (53 to 43 percent), while the Washington Post poll has Obama ahead of Romney by 8 (52 to 44 percent).

A third survey conducted by Gravis Marketing, a call center whose automated surveys do not sample cell phones and that consistently produces more Republican-leaning results, found a smaller lead for Obama (45 to 44 percent). The Gravis numbers were the closest margin for Romney among the recent polls. Three other Ohio polls released in the last week gave Obama leads varying between 3 and 7 percentage points.

The HuffPost Pollster tracking model, which also corrects for pollster "house effects" -- consistent differences across polling firms -- currently gives Obama an advantage of just over six percentage points.





In Florida, a state widely considered a must-win for Romney, results ranged from a whopping 9 point Obama lead (53 to 43 percent) on the new CBS/Times/Quinnipiac poll, to a 4 point Obama advantage on the Washington Post poll (51 to 47 percent), to a much narrower 1 point edge for Obama (48 to 47 percent) on a Tampa Bay Times/Miami Herald/Mason Dixon poll.

Most of the other polls have been closer to the Post and Mason-Dixon results. The HuffPost Pollster tracking model, which combines results from all public polls -- national and statewide -- to produce an estimate for each state shows Obama leading in Florida by just over five percentage points.
