Among likely voters, Obama led his Republican rival by a percentage point, 49 percent to 48 percent, a 3 percentage point swing in Obama's favor from a week ago, but a reflection that the race remains statistically a dead heat, results from the Politico-George Washington University Battleground Tracking Poll released Monday indicated.
Obama held an 8 percentage point lead among those who have already voted, 53 percent to 45 percent.
Among women, Obama had an 11 percentage point lead, 54 percent to 43 percent, over Romney, results indicated. The gap had narrowed to 6 percentage points a week ago.
Men indicated they prefer Romney over Obama by 12 percentage points, 55 percent to 43 percent.
Results also indicated 43 percent say they will "definitely" vote Romney while 42 percent said they'd "definitely" vote for the president.
Results are based on a nationwide telephone survey of 1,000 registered likely voters conducted Oct. 22-25. It has a margin of error of 3.1 percentage points.
