Yes, the Framers and 17 guys on the internet. I have seen all this before too many times to count. I'll take Mark Levin's word over mysterious internet constitutional expert.
I'll bet that I have researched more about this than Mark (Big Mouth) Levin has. He isn't the best authority on this issue. He just thinks he knows everything. I think he's just a BLOWHARD, as many others do, per his low ratings.
The Supreme Court has no problem understanding. It acknowledged three ways that one could be considered a citizen at birth ... A) by virtue of being born in the country to citizen parents, B) by being born in the country without reference to the citizenship of the parents (which it qualified as being with doubts that must be resolved), and C) by being born abroad to a citizen father via the Naturalization Act of 1790. Only ONE of these types of birth citizenship was characterized by the court as natural-born citizens per Article II. Guess which one that was.
