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?
Well good luck with your case. I tried to tell you that court precedent would strike you down in a heartbeat, but if you’ve got time to kill...
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.
