CHARLOTTE, N.C. (AP) — Democrats ridiculed Republican Mitt Romney as a man who "quite simply doesn't get it" and worse Tuesday on the opening night of a national convention aimed at propelling Barack Obama to a second term in the White House despite high unemployment and national economic distress.
Obama "knows better than anyone there's more hard work to do," said San Antonio Mayor Julian Castro, the convention keynote speaker, sharing the prime-time spotlight with First Lady Michelle Obama.
After the deep recession, Castro said in excerpts released in advance, the nation is making progress "despite incredible odds and united Republican opposition." He pointed to the creation of 4.5 million jobs since the president took office.
Obama was back home in the White House after a campaign appearance in Virginia earlier in the day. He said he'd be watching on television when his wife spoke.
Polls made the race for the White House a tight one, almost certain to be decided in a string of eight or 10 battleground states where neither the president nor Romney hold a clear advantage. And during the day there was ample evidence of an underperforming economy, from a report that said manufacturing activity declined for a third straight month to the Treasury's announcement that the government's debt exceeded $16 trillion at the close of the business day.
Castro, the first Hispanic chosen to deliver a keynote address, was unsparing in criticizing Romney, even suggesting the former Massachusetts governor might not even be the driving force on the Republican ticket this fall.
"First they called it 'trickle down, the supply side," he said of the economic proposals backed by Republicans. "Now it's Romney/Ryan. Or is it Ryan/Romney?"
"Either way, their theory has been tested. It failed. ...Mitt Romney just doesn't get it," Castro said. Romney's running mate if Wisconsin Rep. Paul Ryan.
In his campaign trip to Virginia earlier in the day, Obama told an audience at Norfolk State University that the economy will get worse if Romney wins the White House this fall and that Election Day apathy was his enemy — and theirs.
Republicans are "counting on you, maybe not to vote for Romney, but they're counting on you to feel discouraged," he said. "And they figure if you don't vote, then big oil will write our energy future, and insurance companies will write our health care plans, and politicians will dictate what a woman can or can't do when it comes to her own health."
"They're counting on you just to accept their version of things," he said.
On the final stop of a pre-convention campaign circuit of several battleground states, the president also dropped off a case of White House-brewed beer at a local fire station.
A few hours later and hundreds of miles distant, Rep. Debbie Wasserman Schultz of Florida, the Democratic party chairwoman, opened the three-day convention to the cheers of delegates.
The Time Warner Cable Arena's conversion to the Democrats' made-for-television convention hall was complete. The lectern rested on a blue-carpeted stage, inside a circle of white stars suggestive of the presidential seal.
Opening night speakers included Senate Majority Leader Harry Reid of Nevada, who claimed without any proof last month that Republican challenger Mitt Romney may not have paid income taxes for years despite his wealth.
Romney denied it, and Reid refused to say who had told him otherwise.
The Republican challenger was in Vermont as the Democratic convention began, preparing for three fall debates with Obama almost certain to be critical to the outcome of the election.
As was the case with Romney's convention last week in Tampa, Fla., several TV networks said they would carry only one hour of the Democrats' proceedings on live television. Obama's high command reserved the time for the convention keynote speaker — and the first lady.
To laughter from his Virginia audience, Obama explained why he was ceding the opening-night spotlight to his wife.
"A political convention is "just like a relay, and you start off with the fastest person," he said.
"So I'm going to be at home and I'm going to be watching it with our girls. And I'm going to try not to let them see their daddy cry, because when Michelle starts talking I start getting all misty."
Mrs. Obama said before her speech she hoped 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."
There was no shortage of political calculation behind the program of the convention's first night — or for any other.
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.
Protesters briefly blocked an intersection a few blocks from the Democratic convention center, coming close enough to delegates to exchange slogans.
"Four more years," shouted Obama's supporters.
"No more years," came back the reply.
