From the Kansas City Star:
Among the speakers was Thomas Tabback, a novelist and the co-writer of Joe the Plumber's book, "Joe the Plumber: Fighting for the American Dream."
Tabback implored the crowd to fight against a rising "socialist evil" and return the country to its historical greatness. He won the biggest reponse, though, on a double entendre.
"Kings destroy societies, and we got a whole slew of kings up there right now," Tabback said, pausing for effect. "And some queens."
The crowd roared, and at least one gave voice to the statement's implication, yelling out "Barney Frank!"
