ROTFLMAO...
Are you being deliberately dense or are you just like this?
UK law has little to do with American law other than this: Barack Obama Jr. BY BRITISH LAW inherited his father’s citizenship at the instant of his birth. Obama himself says he was born subject to British law. It’s on his website!
He was born a dual citizen, and because of that, by definition, he cannot be... never could be, a Natural Born Citizen. He had more than one citizenship at birth. He could today become a full on British citizen, so too could his daughters.
Natural Born Citizen means you have and have only ever had the citizenship of one nation, in the case we are discussing, American Citizenship.
Obama is an Usurper and should be removed from office. His pretense is a crime against the constitution.
