Hasn't anyone done this?
Lots of people have done it. In March Obama’s name was not in what the HDOH called the 1960-64 birth index, but now it is. See http://myveryownpointofview.wordpress.com/2010/07/27/ya-cant-always-get-what-ya-want/
There are other anomalies too. In the most recent image of the 1960-64 birth index, notice that right above “Obama II, Barack Hussein” is “Obado, Duplicate Mae”. There is no other Mae Obado though. The name which is at the place that Mae Obado would be if there was a duplicate record for her.... is “Obama II, Barack Hussein”.
