On the heels of a powerful address and endorsement from former President Bill Clinton, President Barack Obama aims to persuade economically strapped middle class America to return him to the White House closing out the Democratic National Convention.
"Nothing's more powerful than voices calling for change," Obama told supporters on a pre-speech conference call, reasserting ownership of his optimistic slogan from the 2008 campaign after four tumultuous years in office.
The convention's final night also included an acceptance speech from Vice President Joe Biden.
Actress Eva Longoria was on the program, as well. "No empty chairs," she said, a reference to actor Clint Eastwood's mocking reference to Obama at Romney's Republican National Convention last week in Florida.
Convention planners shoehorned a few more seats into the Time Warner Cable Arena for Obama's remarks, pushing capacity to about 15,000. Even so, the decision to scrap plans to hold the night's session in a 74,000-seat football stadium meant a far smaller crowd than the president's campaign hoped would hear him speak and present an enthusiastic show of support on television.
Officials blamed the switch on weather concerns, and there was heavy rain at mid-afternoon. Perhaps typical of delegates and their feelings, Grifynn Clay of Snohomish, Wash., said, "I would've enjoyed the stadium, but if it was pouring I would not want to be in there for the six hours of speeches."
Obama's aides said he would use his time on the podium to lay out a second-term approach for the economy, which is struggling through the slowest recovery in generations with unemployment pegged at 8.3 percent.
The economy is by far the dominant issue in the campaign, and the differences between Obama and his challenger could hardly be more pronounced.
Romney wants to extend all tax cuts that are due to expire on Dec. 31 with an additional 20 percent reduction in rates across the board, arguing that job growth would result. He also favors deep cuts in domestic programs ranging from education to parks, repeal of the health care legislation that Obama pushed through Congress and landmark changes in Medicare, the program that provides health care to seniors.
Obama wants to renew the tax cuts except on incomes higher than $250,000, saying that millionaires should contribute to an overall attack on federal deficits. He also criticizes the spending cuts Romney advocates, saying they would fall unfairly on the poor, lower-income college students and others. He argues that Republicans would "end Medicare as we know it" and saddle seniors with ever-rising costs.
With two weeks of big conventions concluding, what will be the ultimate impact?
"You're not going to see big bounces in this election," said David Plouffe, a senior White House adviser. "For the next 61 days, it's going to remain tight as a tick."
The campaign focus was shifting quickly — to politically sensitive monthly unemployment figures due out Friday morning, and the first presidential debate on Oct. 3 in Denver. Wall Street hit a four-year high a few hours before Obama's speech after the European Central Bank laid out a concrete plan to support the region's struggling countries through buying bonds.
Romney wrapped up several days of debate rehearsals with close aides in Vermont and is expected to resume full-time campaigning in the next day or two.
In a brief stop to talk with veterans on Thursday, he defended his decision to omit mention of the war in Afghanistan when he delivered his acceptance speech last week at the Republican National Convention. He noted he had spoken to the American Legion only one day before.
He also said he had no plans to watch Obama on television.
