Obama Holding Off Romney in Wisconsin, Michigan According to Latest Swing State Polls with Four Days Until 2012 Presidential Election Day

Only four days are left between now and Election Day on Nov.6, and in the closing hours of the presidential race, President Barack Obama is holding slender, but apparently stable leads in key swing states Wisconsin and Michigan.

A new EPIC-MRA poll released Wednesday projected Obama leading by six points ahead of GOP candidate Mitt Romney, 48 percent to 42 percent. The poll of 600 voters was commissioned by the Detroit Free Press and CNN affiliate WXYZ, CNN reported.

"The survey of 600 likely voters are clearly voting along political party lines with Independents breaking in favor of President Obama, 39 - 36 percent among men, and 44 - 27 percent among women," WXYZ reported.

Bernie Porn, president of the EPIC-MRA polling firm that conducted the survey, tells WXYZ that President Obama is ahead in Michigan because "his favorability is up, he saved the auto industry, and his supporters have a somewhat higher level of enthusiasm for him."

Real Clear Politics polls for Oct. 29 seem to back that theory. With the exception of one Oct. 23 poll from Foster McCollum White Baydoun, which showed a tie between Romney and Obama at 46 percent, the average of new polls have Obama with a 3 point advantage over Romney, 47.7 percent to 44.7 percent.

Meanwhile in Wisconsin, the average of polls on Real Clear Politics are showing a little bit of daylight between Obama and Romney, with the president averaging a five-point lead ahead of Romney in most recent polls, 50 percent to 45 percent.

A poll of 750 likely voters from Rasmussen Reports released Oct. 29 shows a dead heat between Romney and Obama, tied at 49 percent.

However, a poll of 462 likely voters from Wisconsin Public Radio and St. Norbert College, with a margin of error of 5 percent, shows Obama with a sizeable nine-point lead over Romney, 51 percent to 42 percent. And another poll of 1,065 likely voters from NBC News/Wall Street Journal/Marist released on Wednesday shows Obama holding a three-point edge, 49 percent to 46 percent.

"To be at 49 or 50 is a good number this close to Election Day," Marist pollster Lee Miringoff told NBC of Obama's numbers, the Washington Post reported. "But he doesn't have to look far over his shoulder to see that half of the electorate isn't with him and Romney is close."
