Really I'm not really a Palin supporter but if the best thing you have against her is confusing north and south (In word only) as she has clearly stated before that north Korea is the enemy so she grasps that concept just fine. Then you have not much. In fact many presidents have slipped up in a press conferance or a speech.
I agree. Bush's "Our enemies are innovative and resourceful, and so are we. They never stop thinking about new ways to harm our country and our people, and neither do we." springs to mind.
