Thank you for posting this. I’ve been reading a lot of info such as this, and I’m not sure why it’s so difficult for so many to understand.
Really? If it is so easy to understand why are you having such difficulty?
You don't seem to grasp that congress only has the power of naturalization. They can't create a natural born Citizen with the pen. That's why it's called a Naturalization Act. It can only describe by law who is to be a naturalized Citizen.
Regardless, the Naturalization Act of 1790 was repealed by the Naturalization Act of 1795 with the lead of then rep. James Madison and the approval of George Washington and specifically changed "shall be considered as natural born citizens" to "shall be considered as citizens of the United States."
Article II, Section 1, Clause 5 provides that a Citizen of the United States was eligible to be President only if born before the adoption of the Constitution and that thereafter only a natural born Citizen was so eligible. Hence, Congress referring to one as a citizen rather than a natural born citizen, given the presidential eligibility requirements of Article II, was a serious thing.
