Jon Huntsman said today that the continuing sexual allegations against Herman Cain have become a major distraction in the race for the Republican presidential nomination, and Cain should consider dropping out. “Given the bandwidth that has been taken out of the discussion of any other issues pertinent to this campaign, a reconsideration might be in order,” Huntsman told the Globe during an interview. A Georgia woman, Ginger White, has said that she carried on a 13-year affair with Cain.
