WASHINGTON (AP/The Huffington Post) -- Presidential candidate Jon Huntsman is pounding away at rival Rick Perry's skepticism of manmade global warming and criticism of the nation's central banker, saying those stands hurt the GOP and make the Texas governor come off as a not so serious national figure.
Huntsman, a former Utah governor who was President Barack Obama's first ambassador to China, has trailed in early polls nationally and in early voting states, leading his campaign to pledge more aggressive attacks on the top candidates.
Perry, who entered the race last weekend and has surged to a prominent role, has provided Huntsman with an ample opening to take shots.
Perry said in New Hampshire this past week that he didn't believe in manmade global warming, branding it an unproven scientific theory. He also defended the teaching of creationism in schools because evolution "has some gaps to it."
Huntsman responded in a tweet, saying "To be clear, I believe in evolution and trust scientists on global warming. Call me crazy."
