Obama leads 49 to 43 percent over Romney. That’s down from the same poll in late May, conducted before Wisconsin Gov. Scott Walker (R) won his recall election, that showed the president with a 51 to 43 lead.

According to the Real Clear Politics average of polls, Obama leads by 3 percent in Wisconsin, but a survey from conservative polling outlet Rasmussen released last week showed Romney with a 3 point lead.

Still, the Marquette poll is good news for the Obama campaign, as many believed the recall election would energize the GOP base for the presidential election.

President Obama’s job approval rating in Wisconsin is better than his national average, with 52 percent saying they approve versus 43 who disapprove.

Obama has a considerable advantage over Romney in favorability, an issue that has dogged the former Massachusetts governor throughout the primaries.

Fifty-five percent said they have a favorable view of Obama, against 41 who have an unfavorable view. Romney is underwater at 40 percent favorable and 47 unfavorable.

Wisconsin is one of 12 battleground states — the others are Michigan, Florida, North Carolina, Virginia, Colorado, Nevada, New Mexico, Iowa, Ohio, Pennsylvania and New Hampshire — that will be critical in determining the outcome of the 2012 election. 

Wisconsin hasn't backed a Republican for president since Ronald Reagan in 1984.
