The poll, conducted by Marquette University Law School last Thursday through Sunday, shows Obama taking an edge over Romney, who was in a virtual with Obama in Wisconsin two weeks ago, the Milwaukee Journal Sentinel reported. A previous Marquette poll showed Obama with 49 percent and Romney 48 percent.
The Marquette University poll of 1,243 likely voters in Wisconsin had a margin of error of plus or minus 2.8 percentage points.
Both presidential campaigns have been spending time in Wisconsin leading up to Election Day.
Obama stopped in Green Bay Thursday, where he said "our work is not yet done."
"And that's why I'm running for a second term as president -- because we've got more work to do," Obama said.
Republican vice presidential nominee Paul Ryan made three campaign stops in Wisconsin Wednesday, telling voters in Racine, "As Racine County goes, so goes Wisconsin. As Wisconsin goes, so goes America."
"I really look forward to waking up Wednesday knowing we have the country back on the right track," Ryan said at a stop in Ashwaubenon.
