Republicans only demand to see the birth certificates of black Presidents....I'm sure thats a coincidence.
You conveniently ignore that Obama is the only president who has created this type of doubt. You are being disingenuous.
How did he create it? What did he personally do or say that "created" it?
Did he refrain from vociferously denying that he was born in Kenya?
Omitting an action and committing an action are both acts of a person done with their planning and conviction.
It is impossible to accept that he did not know that there is documentary evidence that he was presented as having been born in Kenya.
Where is the documentary evidence that he refuted this.
