Romney campaign may shift focus to Wisconsin in face of Obama lead in Ohio to bag electoral numbers

London - With President Barack Obama maintaining a four point lead in Ohio polls over Mitt Romney, the Republican presidential candidate's campaign is contemplating a shift in its electoral map, according to a report.

The Romney team's pathway to denying Obama a second term in office, which once seemed premised on taking back the Buckeye State, is increasingly shifting focus on the major battleground state of Wisconsin.

Though Romney campaign officials have obviously said nothing in public, Republican sources say the Romney headquarters in Boston is increasingly seeing Wisconsin as a state more apt for flipping, as less campaigning has taken place there, meaning fewer voters have been overwhelmed by political ads, the Huffington Post reports.

Moreover, the Badger State has, in recent months, been more conducive to Republican success and possesses a stronger ground operation, the sources added.

But there are some challenges along the way. For starters, an Obama campaign official said that they feel more confident in Wisconsin than in Ohio, and public polling also suggests the president has a stronger lead in that state. Moreover, if Ohio does go to Obama, it's likely that Wisconsin, with its similar population demographics, will follow suit, the report said.

"Romney/Ryan don't have a clear shot at winning Wisconsin, either, and that still looks like it would take some work. Ryan's presence on the ticket has made it more conceivable, and Priebus coming from Wisconsin indicates that one major decision-maker probably has better instincts about how to best deploy resources in the state," said a Republican source, who spoke on condition of anonymity.
