What absolute crap. This is nothing more than an inadvertent substitution of North for South in the course of talking about a divided country, during an interview where the context from friend to foe changes quickly. It's about as meaningful as the occasional slip of Iraq for Iran and vice versa.
I understand Romney has never made a clearly unintentional slip-of-the-tongue.
Too bad he isn't going to get the nomination, either, so all you Palin bashers had better find yourselves a new boy pretty soon. Romney's current market share is 18%. That's also his ceiling. Bank on it.
