Yes, cheating on your wife is bad. Cheating on her when she's been diagnosed with incurable cancer is just caddish. So maybe that's why Edwards isn't conceding he is the father:

Elizabeth Edwards was diagnosed with incurable cancer in late March of 2007. Rielle Hunter's baby was born in late February of 2008. That means that if Edwards is the father, he was definitely still carrying on the affair with Hunter after he knew his wife's cancer was back.

So when do we get the Maury Povich paternity test? And when will we hear from Rielle? It seems to me that she was obviously the source for much of the Enquirer's reporting. Then there's this strange detail: Edwards is insisting he didn't love Rielle. That should keep her quiet, shouldn't it?
