President Barack Obama is ahead of presumptive Republican nominee Mitt Romney among Michigan voters in the race for president, a new poll shows, and is leading in part because of strong support among women.
Obama was leading 45.1 percent to 39.5 percent in the Glengariff Group Inc. poll, with 15.4 percent undecided; the margin of error is 4 percentage points.
Obama enjoys far stronger support among women, leading Romney 47.3 percent to 35 percent, while being nearly tied with Romney among men, 43.8 to 43.1 percent. The results pose a potential "gender gap" problem for Romney, pollster Richard Czuba said Friday. The Republican needs to be wary of that margin, he added.
In a week in which Obama expressed his support for same-sex marriage, the poll also showed more Michigan voters (44.3 percent) support same-sex marriage than oppose it (43.7 percent). Just over a year ago, half the people polled opposed gay marriage and 38.5 percent supported it.
"I've never seen an issue move so fast," Czuba said. "It may go back a little bit, but I think it's a very clear and dramatic trendline moving toward support of same-sex marriage."
