I fail to see how this has any bearing on Obama's eligibility. "Allegiance by birth" means you were born within a certain country and under their jurisdiction. Obama's allegiance by birth was to the United States, since he was born in the State of Hawaii.

Obama's own people admit he was a British Subject at birth, and became a Kenyan citizen upon that country's independence. But the latter doesn't really matter, it's his status at birth that counts.

Citizens are either native-born or naturalized. Native citizens may fill any office; naturalized citizens may be elected or appointed to any office under the Constitution of the United States, except the offices of President and Vice President.

You'll notice that says NOTHING about "Natural Born Citizens". It is you who are equating "born citizens" with "natural born citizens" even thought the Supreme Court has ruled that those born citizens, but born outside the US, under statute law, are not even native born, they are naturalized at birth, because naturalization is the only power Congress had to confer citizenship.

There are six prior presidents with at least one foreign born parent.

Read it again. It's clearly saying native-born citizens are natural-born citizens, because "Native citizens may fill any office" which includes the Presidency.
