Obama’s place of birth is relevant because NEITHER of his claimed parents could transmit citizenship to him.
If Obama was not born in the U.S., he is an ILLEGAL ALIEN.
And there is no evidence he was born in the U.S.
Correct, hence the issue of where Obama was born. If you read the Tribe/Olson opinion on McCain's eligibility, you will see they say that Obama is eligible because he was born in Hawaii. Thus, it doesn't matter, according to them, what citizenship his parents had. Obama received his citizenship thru jus solis.
And there is no evidence he was born in the U.S.
We have his phony birth certificate, both short and long forms, and he has a US passport. He was never naturalized. There is plenty of evidence he was born in the US, the problem is whether it is fraudulent or not.
