Should we now refer to him as Barack O'Bama since he's suddenly Irish?

He said he went back to Ireland to find the missing apostrophe. I think he may have found it, today. I am very amused at all the stunned looks on the faces of the birthers, who rooted around Kenya for the last 2 years looking into his father's side of the family, and completely neglected looking into his mother's side. Obama is not 'suddenly' Irish, his great great great great Grandfather, on his mother's side, immigrated from Ireland to the USA in 1850.
