What exactly is the purpose of this thread?
There is nothing in the Constitution of the United States about "natural born citizenship", and much less does the Declaration of Indepence have anything to do with that, but just to the contrary, it would defend immigrants to become protected from "natural born" tyranny and false forced obligation.
Senators need a minimum of 9 years as citizens to exercise their function, AND CANNOT be inhabitants of the state they represent. One of the senate's function is to choose the President. There is no requirement for the President, except for being chosen by the senate.
I think you may have misunderstood them.
No Person shall be a Senator who shall not have attained to the Age of thirty Years, and been nine Years a Citizen of the United States, and who shall not, when elected, be an Inhabitant of that State for which he shall be chosen.
The wording is a little alliterative, but they're using a double negative. No person who is not, and the like.
If your interpretation were correct, then anyone over 30 couldn't be a senator. As they use the same 'not have attained the age of third Years' language with the age requirement that they did with 'who shall not be an inhabitant of the State for which he shall be chosen.
And obviously, that's not the case.
You are right about my mistake.
I would like, however, to use this opportunity to emphasize how interpretation does not pertain only to the grammar within a given context but also to its syntax, which is what I believe to be largely absent from general analysis of the Constitution (or any other form of literature or historical documentation).
How, for instance, would the quoted paragragh (and the entire rest of Article I) assist us in understanding what "natural born Citizen" or "Citizen of the United States, at the time of Adoption of this Constitution" means? Perhaps we do have to look further than the Constitution itself, but perhaps not. There are few documents or people as authorative as the Constitution itself when defending natural citizens of the United States, after all.
