DOSWELL, Va. – Five days before the election, Republican challenger Mitt Romney and President Barack Obama vied forcefully for the mantle of change Thursday in a country thirsting for it after a painful recession and uneven recovery, pressing intense closing arguments in their unpredictably close race for the White House. Early voting topped 22 million ballots.

Republicans launched a late push in Pennsylvania, long viewed as safe for Obama. The party announced a $3 million advertising campaign that told voters who backed the president four years ago, "it's OK to make a change." Romney and running mate Paul Ryan both announced weekend visits to the state.

The Obama campaign was increasing its ad buy in Pennsylvania following the RNC's move, an aide said while declining to cite how just much the campaign planned to spend.
