It happened again. Three months after a rodeo clown mocked the president at the Missouri State Fair, fans at a Missouri-Tennessee football game Sunday booed when Barack Obama’s name was mentioned during a halftime ceremony. New members of the Missouri National Guard were being sworn in, said Chad Moller, spokesman for University of Missouri-Columbia athletics. But during part of the oath that reads “I will obey the order of the president of the United States” members of the crowd could be heard booing, according to the Missourian.
