It wasn't if, but when. You can imagine Sarah Palin as an action movie heroine on a large ship that's about to blow up. She's in some kind of red leather suit…she's running….running…… There it goes! A huge orange roiling cloud of flame bursts from the hull, and the shock wave of the explosion propels her as she leaps off the bow of the ship to a waiting lifeboat. Oof. The ship, of course, is the SS McCain Campaign and any shred of credibility she had left, and the lifeboat is (wait for it) Fox News. Because credibility really isn't all that important, is it?
