Also, from what I gathered from the news conference it sounded like anybody could get a Hawaiian birth certificate even if born from outside the country. All that would be required would be for the parents to be residents of the State of Hawaii.
If this is the case it's possible that there was a birth certificate. If there was, why would he not just release that (even though he may have been born outside of the US - seems like it would not necessarily reflect that on the birth certificate).
Or, perhaps there is no birth certificate. At least not from Hawaii.
The explanation that best fits the facts to my mind is that Grandma Toot tried to file something with the Hawaii DoH in August 1961.
This filing is what triggered the newspaper birth announcements.
But the birth claim that Grandma Toot filed was a half-handwritten, half-typed dodgy paper that if anyone actually looked at, would raise more questions than it answered.
So Obama’s solution was to come up with a birth certificate that looked like a normal document someone born in a hospital would have, and so hopefully questions wouldn’t be raised as to whether he was really born in Hawaii.
