Poll: Obama Has Slight Advantage in Michigan

President Obama holds a slight lead in Michigan, according to a new Detroit Free Press poll released on Tuesday.

Obama polled at 48 percent, a six-point advantage over Mitt Romney. When asked about the candidate’s favorability, however, the president’s advantage over the presumptive Republican nominee jumps to a nine-point lead at 49 percent. The two candidates are about even when it comes to unfavorability, with Obama at 46 percent and Romney at 48 percent.

The president also leads Romney in three other swing states—Florida, Ohio and Pennsylvania—according to new Quinnipiac University/CBS News/New York Times polls.

Michigan, a state Romney once called home and where his father served as governor, benefited from the auto industry bailout, which Obama supported and Romney opposed. However, the Romney campaign released a new ad on Wednesday that addresses the bailout, saying it hurt local businesses like car dealerships.

The poll was taken among 600 active or likely voters from July 24 to July 31, with a margin of error of four percentage points.
