What’s the real reason Karl Rove resigned?

You can take a poll at Mad Kane's. Here's a few of the choices:

Karl has a deal to write a George Bush bio and has always wanted to write fiction.

Needs more time to blow Jeff Gannon.

He made the DC Madam's List

Rove wants to write memoir: "I, Turd Blossom" with first scratch and sniff cover

Something else has come up, and he left to cover it up

She even let me add one:

Rove going to Paraguay to pave the way for when Bush flees U.S.

I don't really care why he left. I just wanta see his slimy ass in prison.
