I just watched parts of Herman Cain's press conference in which he repeated his flat denial of all the accusations of sexual harassment. I turned down the sound during most of it. I've gotten pretty tired of listening to him and his shallow bravado. He has a few ideas and they mostly sound vague and half-baked. I turned away from him when I realized he was proposing a national sales tax. Now the accusations aren't anonymous or unspecific. Two women have come forth publicly and given us their stories. Cain called them liars and "troubled" and suggested that the Democrats were behind it. I don't know whom to believe, but Karen Krashaar doesn't seem like a liar or mentally unstable. Cain is betting his credibility against all comers.
