Whether or not Obama was born within the boundaries of the United States has been a hotly argued topic by maybe 10% of the population. In my opinion the jury's still out.
Whether he is a "natural born citizen" even if born in the USA is a hotly argued topic by perhaps 0.05% of the population. No one else really cares. Not even Donald Trump went there.
..there many who argue differently. If the country wants the criteria changed...
Those who "argue differently", (including me) see no requirement that any criteria be changed. I'd happily vote for Jindal for president any time he's on the ballot.
Unless Obama’s father is somebody other than Barack Hussein Obama Sr. of Kenya, he is not a natural born citizen at all. BHO, Sr. was never any kind of citizen of the US and his mother was too young to confer her citizenship on him, according to hawaiian law at the time. At best, he is a dual citizen of Britain and the US — a fact he stated in his Bio.
Now, if his real father is somebody else, then he is (perhaps) a natural born citizen. But, where does that leave his adoption by Lolo Soetero and little Barry Soetero’s declaration of Indonesian citizenship? Did he ever reinstate his US citizenship after Ann Dunham divorced his adoptive father? Since all of the records are deliberately sealed, we’ll never know.
The questions linger.
