“Natural Born Citizen” means:
“A Citizen at time of BIRTH!”
Clearly, a person born on U.S. Soil is a citizen at birth.
There is NO law that would show otherwise, at the time that Obama was born.
If Obama was born in Hawaii, then Obama WAS a “Natural Born Citizen” -—
But, even if Obama was born on US Soil, did Obama later RENOUNCE his citizenship?
In that case, Obama would either STILL be an alien, if not a Citizen, or Obama would be “naturalized” if he again regained his citizenship.
You are confusing natural born with native born.
