Last night, the gloves came off as seven Republican presidential hopefuls squared off in the Las Vegas debate hosted by CNN. As a new frontrunner in the race, all eyes were on Herman Cain at the start of the night. His GOP rivals took turns slamming his “9-9-9” plan to reform the tax code. Rick Perry said, "You don't have to have a big analysis to figure this thing out. Go to New Hampshire, where they don't have a sales tax, and you're fixing to give them one." Despite the attacks, Herman Cain still holds a narrow lead in the latest NBC News/Marist polls. Among likely Republican voters in South Carolina, the former Godfather’s Pizza CEO beats former Massachusetts Governor Mitt Romney by 4 points, just barely outside the margin of error. In Florida, Cain is in a statistical tie with Romney, with Rick Perry following in 3rd with just 8% support.
