Polls show the first lady is more popular than her husband. With the economy struggling, Robert Gibbs, a campaign surrogate and former White House press secretary, said Mrs. Obama "can really tell the story of his (the president's) values, his upbringing, what he believes and what he wants to do yet for this country."
Democratic delegates bestow their nomination on Obama and Vice President Joe Biden on Wednesday night, the same night that former President Bill Clinton delivers a prime-time speech aimed at voters disappointed with the results of the past four years yet undecided how to cast their ballots.
Clinton presided over eight years of economic growth as president, and his own opinion poll ratings have risen since he left the presidency 12 years ago, shadowed at the time by his impeachment in connection with a dalliance with White House intern Monica Lewinsky.
White men favor Romney over Obama in public and private polls, but a Gallup survey taken in July showed the Clinton was viewed favorably by 63 percent of the same group, and unfavorably by only 32 percent.
Among white non-college graduates, another group where Obama struggles, Clinton drew 58 percent favorable ratings and 36 percent unfavorable in the same poll.
Obama's acceptance speech caps the convention on Thursday night at the 74,000-seat Bank of America football stadium. Aides kept a wary eye on the weather in a city that has been hit in recent days with strong afternoon rains.
Republicans did their best to rain on Obama's convention, whatever the weather.
Vice presidential candidate Paul Ryan spoke in Westlake, Ohio, standing behind a lectern bearing a sign that read "Are you better off?"
It was one more jab at Obama's economic record, and at the Democrats' inability to answer the question directly in a round of television interviews on Sunday.
They have since settled on an answer — Yes.
But Republicans didn't stop with the sign on their stage.
They released a web video that interspersed images of Obama and the economy's weak performance with slightly out-of-focus video clips of former President Jimmy Carter discussing the nation's economic woes when sat in the Oval Office more than 30 years ago.
Officials said Republicans were stockpiling cash for the fall campaign. Romney raised more than $100 million for the third month in a row in August, officials said.
Many delegates said emphatically they were better off than when Obama took office, but not all cited pocketbook issues.
""I'm 100 percent better off than I was four years ago because as a young person and as an LGBT American, Obama has done wonders for our community. He's kept student loan rates down, repealed 'don't ask, don't tell' and embraced marriage equality. These are all important things," said Aaron Wilder, a delegate from Oklahoma City.
Matthew Daly reported from Norfolk, Va. Associated Press writers Steve Peoples in Ohio, Kasie Hunt in Vermont, Jack Gillum in Washington, Thomas Beaumont in Des Moines, Iowa, and Ken Thomas and Matt Michaels in Charlotte contributed.
