This is not some Republican witch hunt against Bob Wise. That is NOT the point, and Republicans didn't have anything to do with exposing the affair, requesting release of the public documents making having to do with the affair . . . But as a campaign issue: it is fair to say that you can't trust Bob Wise. He's a liar. It is fair to say that Bob Wise won't work to uphold the traditional family structure and high standards of personal conduct. He has attacked both personally while in office. Those are two issues, at least, where Wise has failed just because of this affair. You think that's perfectly fine?
Personally I think it is important for this type of thing to be fully investigated to determine whether or not laws were broken, that sort of thing. If they were, they should be prosecuted; if not, people should know that too. You don't think people deserve to see for themselves?
Besides that, it's really incomprehensible to me how you don't think morality has any effect on politics. Governor cheats on his wife? That makes him a liar and a destroyer of families, and a failure to his own. Most people expect the government to try to uphold the fabric of society, not help tear it down. This is a lot more that "two consenting adults". That is the Clinton defense.
