One potential problem with a first-time candidate is that the person may not have been thoroughly vetted. Case in point: Politico reported that at least two female employees complained about sexually suggestive behavior by GOP presidential candidate Herman Cain when he was the head of the National Restaurant Association in the 1990s. The women ended up receiving financial payouts to leave the association. The agreements also barred them from talking about their departures. Cain and his campaign repeatedly declined to respond to questions about whether he ever faced allegations of sexual harassment. But after the Politico article came out Sunday, Cain acknowledged to Fox News that he had been accused but said he was innocent. "I have never sexually harassed anyone," he said.
