Why should he? As not terribly bright as he is, McCain has at least a shred or two of common sense. The woman has spent all of her post-vice-presidential bid time totally trouncing her former campaign, complaining that no one was around to pray with her prior to the debates (and even then, Jesus can only do so much) and how both the campaign and the media treated her with sexist attitudes. Let's be real. No one knew who the hell she was until she had a taste of that national spotlight. Now she's willing to get in touch with her inner pageant queen to reign it back in no matter what the personal humiliation.
For as high-and-mighty she claims to be regarding motherhood and special interests, she just doesn't know when to give up, now does she?
I say, let her run right alongside Limbaugh or Jindal or Sanford or whomever. Palin/Crackpot 2012. Bring it on!
