CHARLOTTE, N.C. -- Citing the potential for severe weather, President Barack Obama scrapped plans to accept the Democratic Party's nomination Thursday in an outdoor stadium and moved his convention's final night indoors.
The switch was as much about trying to mitigate political risk in a key Southern battleground as it was about public safety.
Democrats worried Obama would look incompetent or anger voters in the closely contested state if he switched speech sites on the day of the speech or held a rain-soaked event. But the move led Republicans to play up his standing in the state, arguing that he didn't have enough support to fill the 74,000-seat Bank of America Stadium.
Obama squeaked out a win in North Carolina in 2008, but polls show him trailing Republican rival Mitt Romney two months from Election Day.
The weather call means the president will now address a far smaller crowd indoors in the same hall where Democrats have gathered for the first two days of their convention. The Time Warner Cable Arena will be set up for about 15,000 people -- mostly official convention participants -- when Obama speaks.
That's just slightly larger than the president's biggest crowd this election cycle, though an audience of millions will be watching on television. Vice President Joe Biden will also speak Thursday at the indoor arena.
Republicans, who canceled the first day of their convention due to weather in Tampa, Fla., accused Democrats of downgrading their events because of low enthusiasm.
"You can't believe a thing this administration says," said former New Hampshire Gov. John Sununu, a Romney backer. "Their campaign promised you rain or shine the president would be speaking there. Then when they couldn't get a crowd, they brought it inside. I think those facts speak for themselves."
Democratic officials had said earlier this week that Obama would speak outside if it were raining, but not in the event of severe weather. The National Weather Service said there is a 40 percent chance of thunderstorms on Thursday afternoon, dropping to 20 percent by the time the president was scheduled to speak in the 10 p.m. hour.
It has rained every day since Saturday in Charlotte. Strong storms brought downpours of nearly an inch Monday and Tuesday.
Obama's team feared the threat of storms could cause some people to stay home, leaving the president speaking to a half-empty stadium. They worried that a last-minute move inside would leave tens of thousands of people in downtown Charlotte with nowhere to go. They also fretted about the possibility of anti-Obama hecklers acquiring some of the free tickets to the event and disrupting the president's speech.
