"WND has reported on dozens of legal challenges to Obama's status as a "natural born citizen." The Constitution, Article 2, Section 1, states, "No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President."
So EITHER a NBC or Citizen of US is eligible to become President? Does this mean even if Obama SR was NOT an American citizen, MAO-bama is elgible since his mother was a citizen & he was born in HI? And the latter is another BIG question mark!
No. The POTUS requirements read:
"No person except a natural born citizen, or a citizen of the United States, at the time of the adoption of this Constitution, shall be eligible to the office of President; neither shall any person be eligible to that office who shall not have attained to the age of thirty five years, and been fourteen Years a resident within the United States."

Since there is nobody alive today (or for a very long time) that was a "citizen" at the time of the adoption of this Constitution, then everybody else going forward needs to be a "natural born citizen." The framers put that in there because none of them were "natural born" citizens. They were, citizens of the country after the adoption of the Constitution. Citizens of independent states prior to that going back to the Deceleration of Independence. They grandfathered themselves into the requirement because of the blood, sweet and tears they had just given to gain our Independence. That, and without the grandfather clause, there would not have been an eligible NBC of the United States until at least 1822 (1787 + 35 y.o.), the year the country of the United States of America was born.
