Will it be Cain, Romney, or Perry vs. Obama in the 2012 presidential election? We may not have to wait much longer. The Iowa GOP has set the state’s presidential caucuses for January 3. While Herman Cain has surged to top of national polls, he still lags behind Mitt Romney in several of the early voting states’ polls. Iowa poses Cain’s best chance to steal a win and gain momentum. While Michele Bachmann has stumbled in national polls, she still has 12 percent of the Iowa vote.
