Which version? The one where he condemned the story without denying it? Or when he denied it completely? Or when he denied knowing the details of the settlement? Or when he admitted knowing about one or not the other? He should have consulted with his staff and presented his side of the story once. That's not being hip slick and Clintonesque, because after all look what happened to him when he had to go the multiple story route?
You are obviously looking for a way to dislike Cain. None of his answers constituted a different story. He did not sexuallt harass anyone. A disgruntled employee threatened to sue and a severance agreement was arrived at... none of those things are inconsistent nor are they different stories.
Be sure and vote for Romney or Perry so Obama can be pres again
