Hmm, I don’t recall “show an ID” as one of the requirements in the Constitution. It’s completely absurd that this story keeps getting brought up. It doesn’t help our side, it only helps Obama. He has already given proof of his eligibility, he doesn’t have to do more just because a bunch of conspiracy theorists reject either the authenticity or the relevance of the document. The courts are obviously satisfied. 99% of Americans are pretty much satisfied. The bantering of a small minority on the Internet cannot and will not change the fundamental truth the Obama is an American citizen and is eligible for the presidency.
An image was posted to a website or websites, with the certification number blacked out, which invalidates the "certificate," regardless of whether this image is otherwise authentic or not.
So, no, he hasn't given proof of his eligibility.
He hasn’t. Some website named factcheck.org put up a forged document. If he has based his candidacy on a forgery then he is complicit with factcheck.org in committing fraud.
