Could be you’re right but I have always wondered why Wayne Allen Root says he never knew him even though he was attending Columbia and studying political science at the same time Obama was supposedly studying political science at Columbia. Root says NO ONE remembers him from Columbia. Unless Root is making up the whole story Obama was NOT AT Columbia when he says he was. You cannot attend a school and have no one remember you unless you are invisible which Obama certainly is not.
Law Schools require a transcript for admission. That doesn’t necessarily mean it came from Columbia. Harvard has hermetically sealed his records, so we don’t know for sure.
