actually, nothen you are challenging the autheticity of EVERY State of Hawai'i COLB ever presented as proof of citizenshipNo. He has not.
Your claim is just a reiteration of the same disputed contention.
The COLB ("C" for CertificatION) is simply NOT the same as a Certificate of Live Birth.
Just take a gander at: American Thinker: Why the Barack Obama Birth Certificate Issue Is Legitimate
Since Hawaii itself acknoweldges that their COLB documents are subject to error in that regard, it would sure seem fair to agree with them.
And no. I have no need to challenge the authenticity of EVERY Hawaiian COLB. I do have the need to go ahead and suggest that appropriate additional verification, in a matter involving the Constitutional eligibility of the President of the Unites States, is a reasonable request.
the COLB IS the verification of being born IN Hawai'i
that alone would be sufficient to prove natural born status
