Sarah Palin Impersonator, Fake George W. Bush Crash Conservative Gathering (VIDEO)

ORLANDO -- Gov. Rick Scott's announcement that Herman Cain won the Florida straw poll was preceded by two surprising opening acts; Sarah Palin and former President George W. Bush.

When Palin first took the stage inside the Orange County Convention Center, there was an audible gasp among the crowd of delegates.

But it was not Sarah Palin. Instead, Patsy Gilbert impersonated the former governor of Alaska and vice presidential candidate, even launching into a rap.

John Morgan later joined Gilbert on stage as Bush and also launched into song.

This is not the first time impersonators have shown up at Republican events.

At February's CPAC in Washington, D.C., another fake Sarah Palin caused a stir and in June, a Barack Obama impersonator was yanked off the stage at the Republican Leadership Conference in New Orleans after mocking the Republican presidential hopefuls.
