The way I see it, this woman is our most likely route to another terribly damaging Republican administration.
It's frustrating, because it seems pretty clear that if Edwards were to drop out, Obama would have crushed her.
On the other hand, someone made a decent argument for supporting Edwards to me the other day. It goes like this: Even if you doubt Edwards' sincerity (which I do), you should still support him, because his anti-corporate message is vitally important, and we should send a message to other politicians that those issues can work for them, that they can get elected by swearing to confront and defeat corporate power. So even if Edwards is bullshit, we should fall for that bullshit, as opposed to other brands of bullshit. If you think about it, it actually makes sense.
On the other hand, Obama's just a better bullshitter.
