Tod Kelly makes a key distinction:

The media treats sexual harassment cases similarly to the way they treat stories about secret mistresses. After all, it’s the sex that sells the story, right? … But sexual harassment isn’t the same as infidelity. Sexual harassment, at the end of the day, is about the abuse of power. What’s more, it’s about a particularly denigrating and malicious abuse of power. I would go so far as to say that if someone has a pattern of perpetrating sexual harassment, he is the last person you want in power over others – and you should vote accordingly.

My view entirely. We have contemporaneous eye-witnesses to one alleged victim's distress:

The sources describe how the woman recounted her allegations against Cain to two members of the restaurant association’s board – sources who include an acquaintance of the woman’s and a person who attended the restaurant association meeting at which the woman lodged her complaint. The sources say the woman told them Cain invited her to his hotel room at the event, and that both the context and the way Cain phrased the invitation made her feel extremely uncomfortable, even incensed.

Either he invited an employee to his hotel room at a social event, or he didn't. If he did, and she felt she had to leave her job subsequently because of how her complaint altered the workplace environment, then it matters. We need to lift the woman's gag-order, and get to the bottom of this.
