As a long as he doesn't push for creationism to be taught in science class, I don't care.
There is a large segment of the population that believes in creationism and since we're a democracy, it's understood that a large segment of Congress will believe the same.
The problem is in the classroom. We do our young people no favors teaching them God created the world in seven days or some form of intelligent design. Science class is about learning the scientific method and how much we've discovered of the natural world through that vehicle. It isn't for biblical political correctness.
