did he not state in his book he was named Barry but later changed his name to Barack later on in his life?
I believe he did so how on earth can his short form which has been shown today state Barack?
Perhaps he meant that's what he wanted people to call him. Like one day somebody wants to be called "Ed" instead of "Eddie."
No, he wasn’t named Barry, he used Barry as a shortned, anglicized form of Barack until Barack served him better.
