I have no proof for this, but I heard it through the grapevine. So here we are.
It makes a terrible kind of sense, when you think about it. You have Super Trial Lawyer, who wants a Super Baby, so he seeks out Super Establishment Woman and they have a "super time" together (koff koff).
Now Obama is Junior Superman, by all accounts. So it fits. And all the Oedipal rivalry starts to make sense now, doesn't it?
I just have to say, though: wait until Obama reads this diary, and, face twisted by shock, goes to seek John Edwards, who while wielding a red lightsaber and speaking through a black mask, says, "Barack, I am your father."
You know it'll happen.
