And to muddy the waters even further, if we're talking about non-legally binding historical opinions, then there is also the interesting case of Mr. Steiukanler.

Sorry about the formatting mess up - it looked fine in preview.

In your example it is important to notice that young Steinkauler was a natural-born US citizen. His parents became US citizens one year prior to his birth.

You cannot extrapolate his case to all persons born in the USA and claim that all native-born citizens are eligible for US presidency.
