Bill's behavior this weekend gives me pause.  It seems to me that  he is in deep emotional trouble.  He may realize that he may have destroyed his wife's campaign.  This would be the second time he has hurt Hillary.  I know he wants to compensate for the deep hurt he caused her in 1998.  That put an awful strain on their marriage.  The next real challenge for the Clintons will be whether they can save their relationship if she loses.  Given Bill's recent behavior, I think he knows that the stakes for him are more than a primary loss.
