This is part of a statement released by the Cain campaign last night, after Cain's fourth accuser got on national television and told her story in detail:

Unfortunately, the media-driven process by which one must seek this opportunity is fundamentally unserious. I have touched on this before – the emphasis on "gaffes," gotcha questions and time devoted to trivial nonsense – and everyone knows the process only became further detached from relevance this week as the media published anonymous, ancient, vague personal allegations against me.

Hey, if people don't want to believe the accusations of Sharon Bialek, that's fine.  But factually, you simply can't call them "anonymous" or "vague".

And you lose credibility by saying so.
