Mike Huckabee has overtaken Mitt Romney in (a way-too-early) survey of Republicans asking who they would support for the 2012 GOP presidential nomination if the primary was held today. A CNN/Opinion Research poll, conducted April 9-11, had Huckabee leading Romney 24 percent to 20 percent. Last month, Romney had the lead by 22 percent to 17 percent. Sarah Palin comes in third at 15 percent closely followed by Newt Gingrich at 14 percent. Texas Rep. Ron Paul gets 8 percent and everyone after that is in low single digits.
