US politicians and science - are their politician brain dead?

As the USA starts its next election campaign I'm seriously worried that the country is likely to end up being run by a brain dead, ignorant and downright dangerous politician from the fundamentalist, anti-global warming, anti-science, isolationist brigade. See this article from the New York Times kindly sent to me by Michael AA1TJ.  Although this is about republicans, there are as many democrats with equally stupid views. It seems you have to be stupid in all things (apart from making money) to make the grade over there.  Seriously, we are talking about the nation that is supposed to show the world a moral lead, to champion policies to safeguard the planet.

American citizens, please use your head when selecting you future politicians as it matters very much.
