In my view, the DOH vital record birth index disclosure is inconclusive as to whether there is "at least one" or "one, and only one" or whether it was amended or unamended. The HI officials seem to me to be too evasive and uncertain as to what specific data trail there would be beginning in 1961 and going forward for the different possible amendment or non-amendment database fields mapping to an alleged short form COLB.
I will not be satisfied or draw any firm conclusions until the entire vital record file is released, as any honorable public official would have authorized before running for office to remove any suspicion of ineligibility.
Leo has since removed his correspondence with Okubo from his website. But I believe he (or TerriK) made a specific request for index data regarding any amended vital records for Barack Hussein Obama or Barry Soetoro and Okubo responded that there were no vital records in the Birth Index that met that requirement.
Danae and rxsid posted on Leo’s blog too. They may remember what I’m talking about or have more information.
