The number you refer to, 151 1961-010641, is the File Number on Obama’s “Certificate of Live Birth”.
This is NOT the serial number of the “Certification of Live Birth” which really is little more than an acknowledgement that a Certificate of Live Birth is on file.
If you went into a bar as a 21 year old, and you were carded, and instead of a license, you produced a letter from your mother promising that your license, shwoing that you were of legal age, was safely tucked away in your mother’s sock drawer, how many drinks would you expect to be served?
The number I gave is the number that was blacked out on the “Certification of Live Birth” released by the Obama campaign. That’s what someone was asking about.
