It's possible that, despite the deal, Graham won't be able to vote against Frist if the latter activates the destruct sequence countdown. If Graham then goes back on the MOU, DeWine will also slither back in his shadow. That would mean Frist breaks the filibusters and makes McCain look foolish all in one shot. BWAHAHAHAHAHAHAHAHAHAHA!!!
