NEW ORLEANS — A Barack Obama impersonator was ushered off the stage after he mocked the Republican presidential hopefuls and joked about the real president's biracial roots to a room full of conservative activists Saturday.

The Republican Leadership Conference turned the podium over to impersonator Reggie Brown, who drew raucous applause from the GOP's supporters when he projected lewd photos of Rep. Anthony Weiner, the New York Democrat who just resigned after the furor over his sexually charged online dalliances with a former porn actress and other women.

Brown later played up the mass exodus of advisers to candidate Newt Gingrich's campaign and said Gingrich's supporters "are dropping faster than Anthony Weiner's pants."

The audience grew more uncomfortable when Brown turned to the candidates who are looking to make Obama a one-term president.

The impersonator took a shot at former Minnesota Gov. Tim Pawlenty, saying Pawlenty missed the conference because "he's having his foot surgically removed from his mouth."

"Don't worry: it's covered under Obamneycare ... along with spinal transplants," Brown said.

Pawlenty has struggled this week after previewing his criticism of former Gov. Mitt Romney's health care overhaul in Massachusetts that was a model for Democrats' national plan. Pawlenty first called it "Obamneycare," a hybrid of "Romneycare" and "Obamacare." But when given the opportunity to use the term while sharing the stage with Romney during a debate Monday night in New Hampshire, he balked.

Pawlenty later said it was a mistake not to offer a stronger criticism.

The impersonator joked about Romney's Mormon faith and about polygamy, and Rep. Michele Bachmann's tea party support.

"Wonder why many minorities have problems with GOP? Hiring Obama impersonator to tell 'black jokes' at SRLC, for starters," tweeted Doug Heye, a GOP strategist who served as the RNC's communications director during 2010. "Our own fault."
