Obama’s testimony won’t matter one whit. No one should seek to impeach the witness here because we aren’t seeking his opinion on whether he’s a citizen or not. I am assuming we already have his testimony on that...in buckets.
What is missing is the evidence he would surely have IF he were born in a US hospital - or indeed this country.
Actually, AFAIK, he's never stated affirmatively that he is a natural born citizen. I guess his books indicate he was born in Hawaii, but not having read them, that might be wrong too.
But I was really speaking figuratively, and including as "witness" the whole litany of pro-Obama sources that state he was born in Hawaii, and that he was *never* a Muslim, even though his school records from Indonesia indicate otherwise.
