The Bloomberg Politics/Des Moines Register Iowa Poll, taken Monday through Thursday, shows Walker leading a wide-open Republican race with 15 percent, up from just 4 percent in the same poll in October. Senator Rand Paul of Kentucky was at 14 percent and former Arkansas Governor Mike Huckabee, who won the Iowa caucuses in 2008, stood at 10 percent.
Bush trailed with 8 percent and increasingly is viewed negatively by likely Republican caucus-goers. New Jersey Governor Chris Christie is in even worse shape, with support from just 4 percent. More troubling for Christie: He's viewed unfavorably by 54 percent, among the highest negative ratings in the potential field. At 9 percent, retired neurosurgeon Ben Carson pulls more support than either Bush or Christie.LINK
