The poll of 816 likely voters, conducted Oct. 17-20 after last week’s presidential debate, has a margin of error of plus or minus 3.4 percentage points. The poll also surveyed 1,000 registered voters who preferred Obama to Romney by 49 percent to 44 percent, with a margin of error of plus or minus 3.1 percentage points.
NBC said in a previous poll conducted before the presidential debates began, Obama led Romney 49 percent to 44 percent.
