Watch McCain  on stage these days when he is standing backup to Sarah.  He hates it!  He fiddles with his wedding ring.  His lips are in a tight line or a forced smile. Obama needs to answer questions about why he is not going after Palin by saying something like:I know it is hard to believe these days but Palin is not my opponent. Lest we forget, John McCain is actually the one at the top of the ticket. He needs to mock the fact that McCain pales in comparison when Palin is at his side. John's explosive temper is already simmering.  Let's remind him of the humiliation he is already beginning to experience. (Beauty queen Cindy McCain is also none to pleased by being upstaged.)
In addition we need to begin mocking and dismantling thethanks but no thanks phrase that is now so deeply embedded with Palin's persona. We need Youtubes and political cartoons created where she is saying TBNT to John.
For example show the two of them in the White House. John asks her to attend some state funeral. TBNT John, I'm taking the Joint Chiefs out for a moose hunt today. Or:  TBNT John, I'm waiting for a call from Putin to tell him what I have decided to do about Georgia.Or Sarah to CIndy:
The phrase has become her strength. We need to make it her downfall.
