Those were also the SSNs that were targeted by ID thieves because they knew there would be little activity on the SSN and it would also be a matter of time before the person would die (being elderly and all).
I also remember hearing that Obama had never lived in Conn and his first job was in Hawaii as a teenager. Therefore his SSN would have shown HI numbers.
As long as crackpot theories such as this keep getting passed around, legitimate questions regarding his Social Security number will continue to be ignored.
