Mickey Kaus appears to be gearing up, like a less charismatic Harold Ford, for a primary challenge to Barbara Boxer. It’s an interesting prospect. But it raises a lot of questions. Politics is a dirty job. Can we really trust a germophobe to do it? And can Kaus conclusively prove that he has never performed an act of sodomy upon a goat, or any other woodland creature? Is California really ready for a senator in his middle ages who obsesses over a man in his mid-20s? One thing’s for sure. It would be irresponsible not to ask.
