"To be clear. I believe in evolution and trust scientists on global warming. Call me crazy." — Former Utah governor and GOP presidential candidate Jon Huntsman, on Twitter Aug. 18, as he sought to differentiate himself from Republican frontrunners like Rep. Michele Bachmann and Texas Gov. Rick Perry, both of whom have expressed skepticism about evolution and climate change. Huntsman came in second-to-last in the Aug. 13 Iowa GOP straw poll.
