Obama, wrapping up a 40-hour battleground state blitz, also headed to his hometown of Chicago and cast his ballot 12 days before Election Day. The stopover was more than a photo opportunity -- it was a high-profile attempt to boost turnout in early voting, a centerpiece of Obama's strategy.
The 2012 presidential contest was expected to cross the $2 billion fundraising mark Thursday, putting the election on track to be the costliest in history. It's being fueled by a campaign finance system vastly altered by the proliferation of "super" political action committees that are bankrolling TV ads in closely contested states. Back on the campaign trail, the president made repeated, though indirect, references to Indiana Republican Richard Mourdock's controversial comment on rape and pregnancy.
"We've seen again this week, I don't think any male politicians should be making health care decisions for women," Obama told a crowd of about 15,000 on an unseasonably warm fall day in Richmond, Va. The president's aides pressed further, using a web video to highlight Romney's endorsement of Mourdock and to accuse the GOP nominee of kowtowing to his party's extreme elements.
Romney, who appears in a television advertisement declaring his support for Mourdock, brushed aside questions on the matter from reporters throughout the day. He centered his efforts instead on turning his campaign's claims of momentum into a more practical -- and ultimately necessary -- roadmap to winning the required 270 Electoral College votes. Ohio is crucial to that effort.
"This election is not about me," Romney told 3,000 people at a southern Ohio manufacturing company. "It's not about the Republican Party. It's about America. And it's about your family." To an estimated 12,000 people at a high school football stadium in Defiance, Ohio, the Republican declared Thursday night: "We have a big election, and we want a president who will actually bring big changes. And I will and he won't."
Romney has disavowed Mourdock's comments, but his campaign says he continues to support the Indiana Republican's Senate candidacy.
Less than two weeks from Election Day, both candidates feverishly campaigned across the country in an exceedingly close race.
Opinion polls show Obama and Romney tied nationally. A new Associated Press-GfK poll of likely voters had Romney up 47 percent to 45 percent, a result within the poll's margin of sampling error. But the race will really be decided by nine or so competitive states: Ohio, Florida, Virginia, North Carolina, New Hampshire, Iowa, Wisconsin, Nevada and Colorado.
The urgent task for both campaigns is to cobble together wins in enough states to cross the 270 threshold.
Obama advisers have identified at least three viable options. Winning Ohio, Iowa and Wisconsin would put him over the top, as would winning Ohio, Iowa and Nevada. A five-state combination of Iowa, New Hampshire, Wisconsin, Nevada and Colorado would also seal the deal for the president's re-election.
Romney's team has yet to publicly outline any specific pathways to 270. Without a win in Ohio, however, the Republican nominee would have to sweep every other competitive state.
That reality was the motivation behind Romney's daylong swing through three Ohio cities Thursday. Obama finished his day in Ohio, too, with a 12,000-person rally on an airport tarmac -- the final stop on his marathon, two-day drive for votes.
"Even though I've been going for about 38 hours straight, even though my voice is getting kind of hoarse, I've still got a spring in my step because our course is right, because we're fighting for the future. I've come to Ohio today to ask you for your vote," said Obama, speaking against the backdrop of Cleveland's skyline and Air Force One.
An upbeat Romney proclaimed his campaign had the momentum heading into Election Day. But there were signs in Ohio, as well as Virginia, that his surge following the first debate might have run its course.
In Ohio, internal Republican and Democratic campaign polls this week showed Obama with a lead, just outside the margin of sampling error.
The race in Virginia remains close. Romney has established a slim lead, but the shift toward him seen during the three weeks of debates has slowed or stopped, internal polls from both parties showed.
Romney is hoping to boost his electoral prospects in part by cutting into Obama's long-standing advantage with women. The AP-GfK poll suggested that effort was bearing fruit, with Romney erasing the president's 16-point advantage among female likely voters.
Obama advisers insist they've lost no ground with women. But their eagerness to highlight Romney's connections to Mourdock indicated some degree of nervousness within the campaign.
Romney's campaign reached out to female voters Thursday by sending Ann Romney on daytime's "Rachael Ray" show, where she prepared her meatloaf cakes recipe and took cameras along on a trip to Costco to shop in bulk for family gatherings. Mrs. Romney said that, with 30 mouths to feed, her family always eats buffet-style and that "Mitt is often at the front of the line."
The Republican presidential nominee also faced fresh scrutiny of his business record Thursday following the release of newly unsealed testimony related to Staples founder Tom Sternberg's divorce. Documents show Romney said he was initially skeptical of the idea for Staples, the office supply chain he lauds as a business success story that he helped create.
Romney also acknowledged in testimony in Massachusetts probate court in 1991 that he and other Staples directors created a special class of company stock for Stemberg's then-wife as a "favor" to Stemberg, who was a speaker at the August Republican convention. Throughout the campaign, Romney has described Staples as a "great American success story" and took credit for its growth to a mega-firm employing nearly 90,000 workers.
Robert Jones, an attorney for Romney, rejected the notion that Romney undervalued Staples stock to help Stemberg.
While the campaigns speed ahead, about 7.2 million people already have cast early ballots, either by mail or in person, according to the United States Elections Project at George Mason University. In all, about 35 percent of the electorate is expected to vote before Election Day. That would be a small increase over 2008.
"I'm told I'll be the first sitting president to take advantage of early voting," Obama said in an email to supporters, urging them to cast their votes before Nov. 6.
As the campaign enters its final days, both sides are focused on winning the increasingly narrow sliver of undecided voters. Obama made a personal appeal to late-deciding voters Wednesday in a conference call from Air Force One. His campaign is also mailing undecided voters copies of a new 20-page booklet featuring Obama's second-term agenda, a collection of policies that have been previously introduced.
The president's campaign also trumpeted the endorsement by former Secretary of State Colin Powell, a Republican who supported Obama in 2008. Powell praised Obama's handling of the economic recovery, telling "CBS This Morning," `'I think we've begun to come out of the dive and we're gaining altitude."
Elsewhere Thursday, GOP vice presidential nominee Paul Ryan showered attention on Virginia, telling voters in Appalachian coal country that winning a close race won't be enough for the GOP ticket.
"The worst thing that could happen is President Obama gets re-elected and we have more of the same with a debt crisis," Ryan said. "The second worst thing that could happen is we get elected by default, without a mandate."
Vice President Joe Biden took time off the campaign trail to attend a prayer service for former Democratic Sen. George McGovern.
