What does "remember it" have to do with anything ? Why should anyone care what YOU consider to be "some citizenship by deed" qualification ? (wold not be natural born anyway) Citing the Ossama assassination (which many on the left believe is illegal) isn't evidence of anything. US code 1401 title 8 controls citizenship question.

The constitution requires the president be a natural born (not naturalized nor delcared) US citizen over 35? yo. According to US Code 1401 code - Obama may qualify on several counts, regardless of where he was born. For example if one of your parents is a USC who resided in the US for more than 5 years after age 14 - then you are a NBUSC, regardless of place of birth.
The president has no requirement by law to reveal his birth certificate. If someone brings a lawsuit in some question and shows credibility evidence that the Pres is not a USC - for example before the election - then the pres would have to defend himself. I suspect he can only be removed from office by a impeachment proceedings.
