Just as no one cares that Obama’s missing father was Kenyan...

Ah, nice try, wise guy ... but it's not about Kenya either, as Kenya did not gain its independence from the UK until Dec. 12, 1963.

“When Barack Obama Jr. was born on Aug. 4,1961, in Honolulu, Kenya was a British colony, still part of the United Kingdom’s dwindling empire. As a Kenyan native, Barack Obama Sr. was a British subject whose citizenship status was governed by The British Nationality Act of 1948.
That same act governed the status of Obama Sr.‘s children.

According to the British Nationality Act of 1948, Barry’s parents could have petitioned to have Barry made a citizen of the UK. He would not be so automatically.

In like manner, Barry’s mom COULD have applied to become a UK citizen - but she did not. After the divorce, it would have been murkier.
