Former Arkansas Governor Mike Huckabee is making a come-from-behind surge in Iowa, sweeping past Rudy Giuliani, Fred Thompson and John McCain to challenge front runner Mitt Romney. Huckabee has tripled his support in Iowa since July, reports the Washington Post. His drive is being fueled by support from Christian conservatives, according to a Post-ABC News poll.
The poll found that 28% of likely GOP caucusers support Romney, while 24% back Huckabee. Thompson came in third with 15% and Giuliani followed with 13%. Almost half of Huckabee's supporters said they will definitely vote for him in January, while just 29% of Romney's backers said they will definitely vote for Mitt.
