So, there were sexual harrassment allegations against Herman Cain a decade ago, Cain denied them, and he is hitting the old charges again hard today.

Cain may not become the nominee or the president, but it won't be because of this.

Yet the story has legs — and the accusers, the details, and the paperwork will all be forthcoming. Remember, bad gets worse.

Reporters will also conduct a microscopic analysis of his explanation, and if there is the slightest difference between today's version and the old records, then this story wouldn’t just have legs, it would have wheels.

But the other GOP candidates can't make a peep. First, they don't need to, and, second, they all want to be the first choice among Cain supporters when he does flame out.
