President Barack Obama has wrapped up a 40-hour campaign blitz to key states including Ohio.
He also made a photo opportunity of casting an early vote in Chicago. He became the first sitting president to cast an early ballot.
On the campaign trail, the president made repeated, though indirect, references to Indiana Republican Senate candidate Richard Mourdock's controversial comment on rape and pregnancy. Mourdock, who was endorsed by rival Mitt Romney, said that when rape results in pregnancy, it is "something God intended."
Romney, who made three campaign stops Thursday in Ohio, didn't respond to reporters' questions about the controversy. But he said in southern Ohio that the election is not about him but about families. Romney ended the day with a big rally in the town of Defiance, where he told supporters he "will bring big changes."
