Has Mrs. Obama Resigned Herself to a Loss?

Or perhaps, is she hoping for a loss? She seems determined to knock the polish off the Illinois Senator every chance she gets. Mickey Kaus comments:

"Snore-y and Stinky": Michelle Obama maybe doesn't need to worry so much anymore that her husband will become a god-like figure requiring her unique humanizing skills. He's losing by 15 points in the Democratic party to someone who voted for the war and hasn't apologized. ...

Some folks think she'd be just as happy to be about to go back to her high profile job and get out of the campaign business altogether. Chances are, that's what will happen.
