“The founding document...The unanimous Declaration of the thirteen united States of America”
I realize people like to pretend there was one continuous national government from the Continental Congress to the present day. But that’s really more of historical or abstract possibly even metaphysical purposes. For practical purposes, until the states ratify the Constitution, there is no federal government as created by the Constitution to recognize you as its citizen. The thing you are a citizen of today, in addition to your state, is the federal government as established by the Constitution.
The Declaration created a free union of states, or declared itself to. But unless it won the war with Britain and eventually adopted the Constitution, the thing you are a citizen of would not exist. You could not be a natural born citizen of the constitutional U.S., nor a president of the U.S. There would be no such thing, because there would be no U.S. under the Constitution.
“the separate and equal station to which the Laws of Nature and of Nature’s God entitle them”
The Laws of Nature and of Nature’s God do not entitle you to be born a citizen of the U.S. That right cannot exist until such time as there is a U.S. to be a citizen of, and that time comes only when there is positive law to make it so.
Gee...ya don’t say!
