The poll of likely voters showed 48 percent planned to cast their ballots for Obama in the Nov. 6 election, while 42 percent backed Romney. Ten percent were undecided or favored a third-party candidate, the Free Press reported. A poll showed Obama with only a 3 percentage-point lead after the first presidential debate Oct. 3.
Another poll showed U.S. Senator Debbie Stabenow with a big lead over challenger Pete Hoekstra.
