Then obviously, you know nothing about the law and the Constitution, as it relates to this issue. Naturally, this leads to the obvious question, WHY are you participating in a thread where you obviously don't have anything to add to the discussion? Oh that's right, because you're an admitted troll, even though that is clearly against the rules here.
I mentioned the two things I mentioned, because those are the ONLY POSSIBLE WAYS under US law that Obama could NOT be eligible to be POTUS. If either parent is a US citizen, no matter where he's born, he's eligible. Alternatively, if he was born on US territory, irrespective of parental citizenship, he's eligible. Obama only needs to pass one of these requirements to be eligible, and he passed BOTH. Furthermore, for any birther nonsense to ever have had any validity, evidence would have had to have been produced in court before he was sworn in, that proved that neither of Obama's parents were US citizens, AND that Obama was born outside of the US. Demanding he prove he was born here is meaningless, because it's already accepted by the courts that he was. The onus would be on the birthers to disprove the facts as they stand, which is of course impossible...
