I have more than an incorrect interpretation of Natural Born Citizen. Obama isn’t one and never was. A dual citizen can never be a Natural Born citizen. The ONLY time a person born with another nationality ( mom and dads) along with that of say Virginia, was the instant after the Constitution was ratified bringing the USA into being until the last grandfathered in citizen died. After that, you had to be born under the sole jurisdiction of the USA in order to be an NBC. The ratification of the constitution made everyone a naturalized citizen, and only then. That grandfathering would not have been NECESSARY if it only took being born on the soil, because it included those with foreign parents. If foreign parents were ok, then many would have qualified,but that’s not what the founders did is it? Or, the founders put in the grandfathering clause because they wanted to ensure that the founders themselves - some of whom were not born on U.S. soil (e.g., Hamilton) - would be eligible to be President.
My friend, NO ONE WAS ELIGIBLE. Forget about the founders, NO ONE WAS ELIGIBLE for POTUS with out the grandfather clause because the United States didn’t EXIST until the constitution was ratified. The Colonies became States, and the specific sovereignty they had before that ceased to exist.
The grandfather clause was there because no one was a citizen or had parents born there until it happened. It had nothing to do with the founders specifically. Sheesh. Maybe you should read something like Roberts Rules, or some other Parliamentary guide.
