Under the Constitution, Joe and Josephine Citizen have NO VOTE for the most powerful office in the world.
So, why would they have a particulary strong interest in his or her eligibility?
No direct vote, true, but that why I said "selected by", rather than "elected by" which was my first draft.
But they have other interests, such as preservation of their Liberty and their freedom. The Constitutional provision in question was written so that the person charged with defending both would have no personal foreign loyalties or ties, his loyalty would be to the United States, and it's Constitution, first and foremost, and pretty much exclusivly.
Obama probalby couldn't get clearance to serve coffee on AF-1. He has too many foreign relatives, including all but one of his many half siblings, and she is a citizen by statute, not a native born citizen, but that much would be OK.
