Herman Cain told members of his campaign staff on Tuesday that he was reassessing whether to proceed with his presidential campaign, an aide confirmed, a day after an Atlanta woman disclosed details of what she said was a 13-year affair with him... Mr. Cain denied the accusations from the Atlanta woman, Ginger White. But he acknowledged that the latest report of sexual misconduct might be more difficult to overcome, considering that the first voting is set to take place in five weeks at the Iowa caucuses. He said that he had not lost his enthusiasm to run, but suggested it was a distraction that could be difficult to recover from.
