Who is his father?
What nationalities does Obama have?
By appearances from your writing, you've throw-in repeatedly and solidly with Barry's Kenyanesian claim. So has it therefore become my responsibility to argue the point?
Barry's Certificate of Live Birth (COLB) and Long Form Birth Certificate (LFBC) have been proven to be fraudulent forgeries. The number and proportion of those that produced those documents are uniformly and--not coincidentally--rife with CIA-connections. They, supposedly our intel agencies, have lied to all of us.
Barry's DNA has no close relationship to Malik Obama.
Barry's DNA has no close relationship to Maya Soetoro Ng.
These facts can only mean that Barry is the child of neither BHO I nor Stanley Ann Dunham. It means that all those CIA-connected folks working on his COLB and LFBC were there to commit a fraud on the American electorate and ultimately foist a two-term usurper into the US presidency. Even if Barry's actual birth particulars plausibly showed him to be eligible for the US presidency, the Deep State would have only had to forge documents that were correct. The true documents have never existed because the intel community has never wanted the facts to come out. (Under that kind of pressure, I don't see why I should make such disclosures here and now.) So, coincidentally, you're right in calling Barry a usurper, but your path you use to do so has many aspects of hurting the cause.
As evidenced by Bill Gates', both his parents', Margaret Sanger's and the British monarchy's demonstrations of complete devotion to eugenics, we can all learn something about the prime value the Deep State places on bloodlines. Both Barry's parents are of the 13-bloodline Deep State, which identifies where they place their fealty in primacy over their passport details, which is in my view appropriate disclosure here. Barry's passport details have been considered interchangeable anyway, just as Barry, his mother, and people like Brennan always treated them.
Barry's donor bio-dad was of the Rockefeller lineage. When you've got that kind of potential "horsepower" behind you, conventional facts and documents be damned around the power available surrounding a US president.
