As someone who lives outside the US and has no dog in this fight (as it were), I'm really hoping she stands for the Republican nomination, purely for the entertainment factor. Every time I see her on TV and hear the latest buffoonery that spills from her mouth, I laugh and laugh and laugh. Still its not my government she potentially could be heading, so I guess I can afford to laugh.
Although now I think about it, she will be in charge of a big bunch of nukes, so maybe I ought to worry more. On the other hand she can't see New Zealand from her house so we should be safe.
