Um, that's exactly why these complaints were unsubstantiated. That means that, after they were investigated, they were found not to constitute sexual harassment.
Wanting to re-open this case is extremely unhelpful, unproductive and unfair. It is closed. It was a long time ago. People can come forward and say all kinds of things that can neither be corroborated nor refuted.
Why would you want this kind of ridiculous distraction brought into the GOP race at this time? This is exactly what the Left wants, however.
If you believe the mere existence of a sexual harassment complaint against Cain is enough to impugn his character or conduct -- even though that complaint was unsubstantiated and closed without any action whatsoever taken against Mr. Cain and, instead, the women were paid-off to shut up and get the hell out of the assocation -- by all means, do what you gotta do.
But don't wish this ridiculous and worthless drama on the rest of us. We are trying to hire someone who can beat Barack Obama in 2012.
Don't tell Romney or Perry -- they'll be so disappointed.
