Everything about Sarah Palin is terrifying - not least the fact that McCain is an old man and it's no secret he's had cancer before, and that if elected he could die or fall too ill to govern before the end of his term. And then...yikes, it doesn't bear thinking about.
Palin may have been chosen as a running mate on an "it's so crazy, it might just work!" basis, but I really hope most voters are clever enough to figure out that actually, most crazy ideas don't work, which is why they're called 'crazy' in the first place.
