Actually, while it might not be sufficient, it might be an element. It's possible in Hawaii and other states to file for a delayed birth certificate, and for non delayed one that alleges a home birth. An entry in the family bible might support or refute the fact of birth at the time and place alleged in the application and accepted birth certificate. But in order to know if the Certification of Live Birth is based on such a "nonstandard" Certificate of Live Birth, one has to see the Certificate, since such information is not on the Certification. Filing as a home birth is just the sort of thing a concerned grandmother might do to ensure her grandchild was a counted as a US Citizen. Something most, even extreme liberals, thought important in 1961. But since the Certification released is a clear forgery, the Certificate could say almost anything.
The State Department will not accept Delayed Birth Certificates, ones that show a date of birth more than a year before the date accepted by the registrar. That's because such are so easy to get for persons born outside the country, and the Certification (or other abstract, different states have different terminology) does not contain enough information to verify that the birth actually took place where and when indicated.
I meant to say "Delayed Abstract/Short form BCs. They will accept long form/vault copies of delayed BCs. Of course they will check the information out more thouroughly than they would a normal BC, short or long form.
1. I don't think even Buckhead thinks it's a clear forgery.
2. Although the Hawaiian authorities in charge of birth certificates have not released information about Obama's vault birth certificate, other than the fact that it exists, I do not believe they they would remain silent about such a public use of a forged certification.
So our own State Department might not even accept Hussein Obama’s so-far-released “credentials” as a natural-born citizen!
