The strange 2008 McCain-Obama
Despite the misinformation being disseminated by our corrupt political-media culture, there is no ambiguity.
According to Article II, Section I, Clause 5 of the Constitution, the narrative of the 14th Amendment, the Supreme Court case of Minor v. Happersett (1875), other legal opinions, precedence and historical background, Presidential eligibility requires that a candidate be born a US citizen of two US citizen parents at the time of birth.
If you are unwilling to accept the exhaustive legal documentation regarding the true meaning of "natural born" citizenship, you may try the common sense question:
Why has every President since Martin van Buren been a US citizen at birth of two citizen parents except Barack Obama and Chester A. Arthur, who lied about his personal history?
In order to understand the political machinations surrounding the 2008 Presidential eligibility debate, it is important to know that there have been numerous recent attempts by Democrats and Republicans to amend the Article II "natural born citizen" clause, starting in 1975 when New York Democrat House Rep. Jonathon B. Bingham introduced House Joint Resolution 33, which clearly recognized the distinction between "citizen" and "natural born citizen:"
"Provides that a citizen of the United States otherwise eligible to hold the Office of President shall not be ineligible because such citizen is not a natural born citizen."
It may be that our corrupt political-media culture, having failed to change the Constitution by legal amendment, achieved it in 2008 by political fait accompli.
On January 25, 2008, before the Super Tuesday Presidential primary vote, the New York Times endorsed Senator John McCain for President.
One month after endorsing McCain, on February 28, 2008, about the time Barack Obama began to overtake Hillary Clinton in the Democratic Presidential primary, the New York Times published an article questioning McCain's eligibility to be President according to the natural born citizen clause of the Constitution. According to the Times article, he was born outside the continental United States on a US military installation in the Panama Canal Zone and, therefore, possibly ineligible. The Times story was immediately followed by numerous other news items questioning McCain's candidacy as well as lawsuits in California and New Hampshire challenging his Constitutional eligibility for the Presidency.
