"Four years ago, America voted for a post-partisan president, but they have seen the most political of presidents, and a Washington in gridlock because of it," he added.
The Republican challenger borrowed a theme from Obama's 2008 campaign, saying he and running mate Paul Ryan "can bring real change to this country." And he tweaked a line that former President Bill Clinton unveiled at this summer's Democratic National Convention, saying, "This is not the time to double down on trickle-down government policies that have failed us." Clinton said last month, referring to policies he said Republicans had tried in the past with poor results, "We simply cannot afford to give the reins of government to someone who will double down on trickle-down."
Democrats delighted in pointing out that Romney spoke outside Kinzler Construction Services, which received more than $650,000 in stimulus funds from the 2009 package that Obama signed into law and the Republican nominee often criticizes.
Romney campaigned in Iowa and Ohio as national polls showed a tight race. Though his aides claimed momentum, citing recent polls, Obama's team said the president led or was tied in each of the nine battleground states where the two sides have concentrated hundreds of millions of dollars in television commercials over the past five months.
Back in the White House after his long day and night and day of campaigning, Obama said he looked forward to trying to reach a deal with congressional Republicans on a sweeping budget deal if he wins re-election. Asked by radio show host Michael Smerconish if he would make the first move, the president replied, "I've said I'll do whatever's required to get this done.
"And I think the key that the American people want right now is for us to tackle some big challenges that we face in a commonsense, balanced, sensible way." That was a reference to one of his biggest differences with Romney his insistence that tax cuts be allowed to expire at upper incomes on Dec. 31, as opposed to Romney's insistence that they be extended.
There was little indication the economy was gathering much momentum, based on Friday's Commerce Department report, which said growth from July through September was slightly faster than a 2 percent annual rate.
Sandy sidetracks candidates' plans
President Barack Obama and Republican Mitt Romney's meticulously arranged travel schedules, a crucial element of their final-stretch strategies, could be upended in the last full week before Election Day by Hurricane Sandy, a super storm barreling toward some battleground states.
The storm also could make it harder for Americans interested in early voting, an important part of both campaigns' efforts, especially Obama's.
Romney and Vice President Joe Biden canceled weekend campaign events in coastal Virginia Beach, Va., though their events in other parts of the state were still set.
