Why didn’t Obama show the people?
I have no idea, this is just a guess.. the only reason I can suspect IF it was an honorable intention (that is a BIG IF) was that he was protecting the privacy act of 74 by not creating a precedent. I know, big stretch assuming there where honorable intentions...
In reality, IF it was legit Hawaii birth, maybe it showed his parent’s weren’t married? Didn’t want bastard jokes?
All wild guesses.
