There has been a recent movement among science blogs and activists to organize a science debate for the presidential candidates. This is, in my opinion, an excellent idea. It would not have to be like a science test, nobody expects candidates to be scientists, but we should expect them to be in touch with reality, and to understand how science affects policy. As our society becomes more reliant upon technology and faces challenges in medicine, energy, defense, and the environment, a scientifically literate president is crucial. I encourage everyone to check out the official Science Debate 2008 website, and read some of the excellent blog posts, and editorials on the topic.
