A disturbing view from Missouri

The Missouri Corn Growers Association placed a number of these billboards across the state earlier this year. That's a white farmer in a polo shirt on the left and the former king of Saudi Arabia on the right.

Not that ethanol doesn't have its advantages (and disadvantages too), but can someone please explain to me how this blatantly racist advertisement makes its point? From the Columbia Daily Tribune:

Becky Grisham, MCGA’s director of communications, said the billboards were designed to bring more awareness to the issue of statewide ethanol standards under consideration in the Missouri General Assembly and the overall effort to promote the homegrown industry. "I think it’s done a pretty good job," Grisham said.

Sheesh. And I thought working in communications at Big Red was bad ....
