Michelle Obama said she wants to use her opening speech to "remind people about the values that drive my husband to do what he has done and what he is going to do for the next four years. I am going to take folks back to the man he was before he was president."
San Antonio Mayor Julian Castro delivers the convention's keynote address Tuesday, a nod to the importance of Hispanic voters in the race.
"Under any score — immigration, education, health care — in any number of issues, he has been a very effective advocate for the Latino community," Castro said of Obama during an interview on CNN.
With flourishes but no suspense, Democrats will march through the roll call of states renominating Obama for president and Joe Biden for vice president on Wednesday.
That's also when the convention hears from Bill Clinton, whose 1990s presidency is being trumpeted by Democrats as the last great period of economic growth and balanced budgets — a further redemption of sorts, at least from his party, for a leader who survived impeachment over sexual scandal.
Obama's big acceptance speech is Thursday, and Democrats are closely monitoring the weather forecast since he's scheduled to speak outdoors at Bank of America stadium.
Obama campaign manager Jim Messina said Tuesday during a panel discussion with ABC News and Yahoo! News that the president's speech would be held outdoors "rain or shine" — unless the weather would put people at risk.
Heavy evening rains doused Charlotte over the Labor Day weekend. Thursday's forecast calls for a chance of rain.
Obama came out with a campaign commercial asserting that, under Romney, "a middle-class family will pay an average of up to $2,000 more a year in taxes, while at the same time giving multimillionaires like himself a $250,000 tax cut." Aides said it would be seen in Colorado, Iowa, New Hampshire, Nevada, Ohio and Virginia, the battleground states where the White House race is likely to be decided.
The president and aides have acknowledged for weeks that they and the groups supporting them are likely to be outspent by Romney, and recent figures say that has been the case in television advertising in the battleground states for much of the past two months.
Democrats chose North Carolina for their convention to demonstrate their determination to contest it in the fall campaign. Obama carried North Carolina by 14,000 votes in 2008, but faces a tough challenge this time given statewide unemployment of 9.6 percent, higher than the vexing national rate of 8.3 percent.
