Herman Cain is the undisputed GOP frontrunner, but he’ll have to get his act together fast to keep the top spot. The Weekly Standard’s John McCormack says Cain actually has a chance at the nomination, but points out that Cain's support "remains very fluid...more than two-thirds said they might end up voting for someone else." That leaves Cain with some major hurdles on the way to the nomination: he has to win Iowa, which he has neglected. He has to be open to modifying his “9-9-9” tax plan, which his opponents will attack for its apparent tax increases. He needs a foreign policy. And most of all, he has to avoid the red-meat rhetoric that has made him look unpresidential in the past.
