I saw the whole 18 minutes on David Shuster, and if listen carefully, getting through the incoherence, a pattern becomes clear. Just as people say JFK's entire inaugural was about the Cold War, her entire press conference address was about the investigations of her going in on Alaska. From the opening lines to the end, the recurring theme was that because she was the GOP VP nominee, the national media and liberals have descended on Alaska and begun one fraudulent investigation after another, costing taxpyers millions. And the vultures won't stop until she quits, so she's leaving for the goood of Alasaka. Therefore, quitting in the face of numerous ethics investigations becomes an entirely selfless gesture on her part.
Make of that what you will.
