Mitt Romney leads President Obama by five percentage points among likely voters in the nation's top battlegrounds, a USA TODAY/Gallup Poll finds, and he has growing enthusiasm among women to thank.

As the presidential campaign heads into its final weeks, the survey of voters in 12 crucial swing states finds female voters much more engaged in the election and increasingly concerned about the deficit and debt issues that favor Romney. The Republican nominee now ties the president among women who are likely voters, 48%-48%, while he leads by 12 points among men.
