Presidential candidate Jon Huntsman has a bone to pick with rival Rick Perry for his comments about global warming and Ben Bernanke. The former Utah governor has been trailing in the polls, leading his campaign to take more aggressive shots against the leading GOP candidates. Last week Perry said he didn't believe in man-made global warming and defended the teaching of creationism in schools because evolution "has some gaps to it." Huntsman retorted with a tweet: "To be clear, I believe in evolution and trust scientists on global warming. Call me crazy." Perry also said he believed Bernanke would be committing a "treasonous" act if he decided to "print more money to boost the economy."
