Not only did they use President Bush as a dummy in 1994, the bull tore him to shreds. And he probably laughed at it!
Another racial double standard.
From the 1994 Philly Enquirer article:
The big white gate flew open. The bull came out bucking. The rider flopped from side to side and the bullfighters held back, letting the bull make his moves until the rider dropped off. Licciardello crouched in a heavily padded barrel, a human target should the bull decide to charge. Hawkins waited near the barrel, holding his big inner tube. A dummy with a George Bush mask stood beside the clown, propped up by a broomstick.
(...)
T.J. Hawkins rolled out the big inner tube, and the bull lowered his head, shot forward and launched into the tube, sending it bounding down the center of the arena. The crowd cheered. Then the bull saw the George Bush dummy.
He tore into it, sending the rubber mask flying halfway across the sand as he turned toward the fence, sending cowboys scrambling up the fence rails, hooking one with his horn and tossing him off the fence.
O’Brahma seems like a natural fit for a rodeo.
