The poll's findings come just ahead of the first general election presidential debate on Wednesday in Denver, Colo. University of New Hampshire pollster Andy Smith said that Romney could benefit from a strong performance in the debate.

"That's the one advantage to have when you are running against a president," Smith said. "Voters tend to vote retrospectively, and if you can remind them of the bad things that happened under a president, they are more likely to believe those things."

The poll was conducted Sept. 27 through Sept. 30 by WMUR and the University of New Hampshire Survey Center. It had a margin of error of plus or minus 4 percentage.
