Watch this interview with Jon Huntsman. Not obviously a sociopath! Prepared to admit the truth of biology and climate science!
Notice that the reason he gives for endorsing evolution and climate change is that it would be politically disastrous not to - “if we become the anti-science party, we will lose the votes of people who otherwise would help us win in 2012.” That’s not a reassuring response, since it implies (absent some additional justification) that with a large change in public opinion, he would be prepared to change his position on those topics. If you’re going to seek a position as the candidate who is both non-crazy and is not Romney, a good place to start would be to avoid calculated and hedged Romney sorts of answers. How about: “I accept evolution and man-made climate change because that’s the best science. I also believe in gravity, a round Earth, and do not believe in fairies or unicorns.”
