Are Herman Cain and Stephen Colbert teaming up against the rest of the Republican presidential hopefuls? Perhaps. The former candidate plans to tape a segment with Colbert on Friday in South Carolina before Saturday's primary. While Colbert is actually not eligible to run in South Carolina, Cain's name remains on the state's ballot despite his having dropped out of the race in December. As such, Colbert ran an ad endorsing himself under Herman Cain's name. "I find it very clever and humorous, as it should be," Cain said of the ad. "Anyone who finds what Mr. Colbert is doing offensive should simply lighten up." Perhaps the two will join forces after all.
