No. If he does, he will find himself out of a job, just as his former congressman, Bob Inglis, did when he himself proposed such action.

Weve never left high school, says Marcia McNutt. People still have a need to fit in, and that need to fit in is so strong that local values and local opinions are always trumping science. And they will continue to trump science, especially when there is no clear downside to ignoring science.
