We've all seen a copy of his birth certificate online. No one has presented any evidence that what has been circulated is not genuine.
Look, all of the evidence, from the birth certificate, to the newspaper announcement, neighbor testimony and the fact that there is not a single instance where anyone who knew him has ever reported that he was born anywhere other than Hawaii, leads to the conclusion that he is a natural-born citizen.
If people want to disprove this, give us some evidence. The crazy theories of his mother flying halfway around the world while 9 months pregnant, then sneaking back into the country a couple of days after his birth are nice stories, but there is no concrete evidence to support this narrative.
No one? It seems several no ones have done just that.
Indeed one of these no ones has been threatened into silence, why do you suppose that is?
