No offense meant but I believe this statement is false.
There are only two kind of citizens, naturalized and natural born. There is no third kind of citizen. McCain never went through the naturalization process, so he is either a natural citizen or an illegal alien.
Assuming Obama was born in Hawaii he instantly became a citizen, and did not go through a naturalization process. Since he is definitely not a naturalized citizen, he is automatically a natural born citizen.
Again there is no third kind of citizen.
No offense taken. But please consider the following from the man who penned the 14th Amendment in 1871. Rep. John A. Bingham gave a definition of Natural Born Citizen, which stated in part:
every human being born within the jurisdiction of the United States of parents not owing allegiance to any foreign sovereignty is, in the language of your Constitution itself, a natural born citizen.

So, to restate Rep. Binghams definition of natural born in 21st century terms:
1. Born on U.S. soil;
2. Parents are citizens at the time of birth.
Im not smart enough to make this stuff up!
