This is getting more and more fun to watch.
The key issue is in this sentence: it is Article Two, Section One of the Constitution which requires that the President be a “natural born citizen” and not simply a naturalized citizen.
Obama needs to produce a witness who will swear that he/she observed Obama’s birth in Hawaii in 1961. It could be a nurse, doctor, friend of his mother, etc. If that witness is not produced, it can be assumed Obama was born in Kenya and his mother then flew back to the US with the infant and fraudulently registered his birth as occurring in Hawaii. Therefore, Obama would be ineligible to be sworn in as president.
