WASHINGTON Potential Republican presidential candidates flocked to a gathering of conservatives on Thursday to road-test a message that basically boiled down to this: Beat President Barack Obama in 2012.
Republicans have no obvious heir-apparent for 2012, leaving 11,000 conservatives at a conference to ponder a crowded field fighting for attention 21 months before the election.
Newt Gingrich, the former speaker of the House of Representatives who is flirting with a run next year, declared that Republican victories in congressional elections last year were only the start. "2010 was the appetizer, 2012 is the entree," he told the Conservative Political Action Conference.
Representative Michele Bachmann, a Tea Party champion often mentioned as a potential 2012 contender, told the group that Republicans' main goal was "making Barack Obama a one-term president."
The party is on a roll after wresting control of the House from the Democrats in November's elections and battling Obama on spending cuts.
But Obama may be hard to beat. He appears to be enjoying an improved standing with Americans by making some centrist moves after his Democrats were routed in the elections.
Celebrity real estate tycoon Donald Trump, a surprise speaker, drew the largest crowd of the day and criticized Obama's economic policies.
Nobody knows whether Trump is serious about running for president. But he came with plenty of talking points, complaining the United States needs to get tougher with China over its currency policy and with OPEC nations for high oil prices.
"If I decide to run, I will not be raising taxes," Trump said. "We will be taking hundreds of billions of dollars from other countries that are screwing us."
He moved briskly from a complaint a German company plans to buy the New York Stock Exchange to a remedy for Somali pirates: "A couple good ships and we'd blast them out of the water."
With his lavish lifestyle and trademark hairstyle, Trump is perhaps America's most famous businessman. He presided over the popular NBC program "The Apprentice" with the signature line "You're fired."
So perhaps it was inevitable that when he declared he would decide by June whether to become a candidate, someone yelled from the crowd, "You're hired."
The crowd loved his performance, including a put-down of perennial Republican presidential candidate Ron Paul.
When Trump said he wished there were a "fantastic" Republican candidate so he would not have to consider running himself, Ron Paul supporters shouted, "Ron Paul" as an alternative.
Trump said: "I like Ron Paul. I think he's a good guy, but honestly he just has zero chance of getting elected."
Everyone cheered except the Paul supporters.
The crowd also got an unexpected appearance from former Vice President Dick Cheney, who introduced former Defense Secretary Donald Rumsfeld.
The gathering came as sniping broke out between two potential candidates -- former Alaska Governor Sarah Palin and former Senator Rick Santorum.
Santorum drew fire from Palin for a television interview in which he seemed to suggest Palin was skipping the conference because she would not be paid for appearing.
"I will not call him the knuckle-dragging Neanderthal ... I'll let his wife call him that instead," Palin told Fox News.
The conference resumes on Friday and will include speeches by possible 2012 candidates Mitt Romney, a former Massachusetts governor, and former Minnesota Governor Tim Pawlenty. It concludes on Saturday with a presidential straw poll.
