Mitt Romney is trying to close the deal with voters by focusing on their economic concerns, an area where polling shows the Republican nominee has an edge heading into the final days of the campaign.

As President Barack Obama takes a break from the campaign trail, Romney was to deliver what his campaign billed as a significant economic address in swing state Iowa. While he was not expected to break new ground, his campaign said Romney would use the speech to help crystalize the differences between the candidates’ economic approaches.

The speech comes on the same day the government showed a slight pick-up in economic growth in its final report before the Nov. 6 election.

The pickup to 2 percent from July to September from the 1.3 percent in the second quarter may help Obama’s message that the economy is improving. Still, growth remains too weak to rapidly boost hiring. And the 1.74 percent rate for 2012 trails last year’s 1.8 percent growth, a point Romney is likely to emphasize.

An Associated Press-GfK poll out this week shows Romney overtaking Obama as the candidate that likely voters trust more to handle the economy. The poll found 51 percent of those voters surveyed Oct. 19-23 picking Romney, compared to 44 percent for Obama. The two candidates were tied among likely voters on that issue in the previous poll in mid-September.

Still, the two are locked in a dead heat in the nationwide poll. Other surveys show a tight race in the swing states that will decide the election, with the winning candidate needing 270 Electoral College votes.

Romney has made particular gains among women after making the case that he’s more qualified to make sure their families and the country are on a solid financial footing. A month ago, women favored Obama over Romney on the economy 56 percent to 40 percent. Now, the split has shifted to 49 percent for Romney and 45 percent for Obama.

Obama has tried this week win over women on a social concern, abortion. On Thursday, the president made repeated, though indirect, references to Indiana Republican Richard Mourdock’s comment that any pregnancy resulting from rape is “something God intended.”

“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 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, has ignored repeated questions on the matter.

Romney also has ignored the criticism and is instead accusing Obama of playing partisan politics in an “incredibly shrinking campaign.”

“This campaign is growing. The momentum is building. We’re taking back America,” Romney told 12,000 supporters in Ohio late Thursday, the same night that media trackers confirmed his campaign was expanding its TV advertising into Minnesota.

The investment is described as a small buy that Democrats suggest is simply intended to generate media coverage and force Obama’s campaign to invest there as well. President Richard Nixon was the last Republican to carry the state, in 1972.

Obama arrived back in Washington late Thursday following a 40-hour battleground state blitz of eight states. He was taking a brief break from the campaign trail Friday and spending much of the day at the White House, with a trip to Democratic Party headquarters to film a live appearance on MTV. Turning out young voters who tend to vote Democratic is a key strategy for the Obama campaign.

The president also planned Oval Office interviews Friday with American Urban Radio Networks, which has a largely black audience, and Michael Smerconish, the conservative-leaning radio host who backed him in the 2008 election.

Obama also planned to talk to local television stations in swing states. And the campaign announced Friday that the president will travel next week to Colorado, Wisconsin and Ohio for a series of campaign rallies and events.

Meanwhile, in Massachusetts, court documents released Thursday revealed Romney created a special class of company stock for Staples founder Tom Stemberg’s then-wife as a “favor.” The testimony had been sealed for almost two decades after Maureen Sullivan Stemberg sought unsuccessfully to alter the divorce agreement that provided her with 500,000 shares of Staples stock.

Romney’s campaign did not address the issue, instead referring questions to attorney Robert Jones.

Jones rejected the notion that Romney undervalued Staples stock to help Stemberg. At the time, Romney insisted the board’s decision was made “in the best interests of the company’s shareholders.”
