According to new CNN/ORC polling, Herman Cain and Mitt Romney are vying for the top spot among the 2012 GOP presidential candidates. The two candidates will join the other GOP presidential hopefuls tonight to go head to head at the Republican debate in Las Vegas, co-hosted by CNN and the Western Republican Leadership Conference.
Although these types of debates have been happening frequently across the country, CNN senior political analyst Ron Brownstein says that they are having an impact on voters. In fact, Brownstein calls the current campaign season a "nation audition" for the GOP candidates.
Today on American Morning, Brownstein joins Carol Costello in Las Vegas to weigh in on the latest polling numbers and to discuss what he is looking forward to at tonight's debate.
