Before you ask, I did not have the will or energy to do it this time around. Another 4 years of this fascist on my tv will be enough motivation.
The definition of a natural-born citizen is by no means legally settled. There’s a controversy, with legal scholars on both sides of the issue. There’s a Michigan Law Review (I think) issue devoted to the topic that is from 2008, I think. I might be mistaken. But the question is not simple. It’s not possible at this stage to “explain” it because there are no authorities that are accepted as definitive on the question. If the Supreme Court would rule on the question, that would be a different matter, but it seems desirous of not touching the question with even a 100-foot pole. It wants to leave the question up to the political system and stay completely out of it. That leaves Congress to specify the meaning of the term. And here we are, folks, with a Congress that also doesn’t want to touch the question with even a 100-foot pole.
