Sexual harassment charges can be ambiguous at the time, let alone 15 years later. Absent some evidence that these charges were much more credible and serious than they sound at the moment, or that this is a pattern with Cain, he’s going to be fine and may come out stronger in the near-term. Getting beaten up by the news media helps a candidate like Cain. By the conventional rules of damage control — get everything out at once and don’t constantly shift your story — yesterday was a lackluster performance, but since Cain has at times been unclear and confusing about his current views, it’s not unexpected that his response would be ragged to this. Last night on Greta, I found him sincere and believable . . . although he makes you a little nervous about what he might remember next.
