Secondary proof of NON US Citizenship....Yes?
"...The document indicates that a consular officer issued a single certificate of statutory citizenship, within the time frame including August 4, 1961, to a child born to a U.S. citizen between July 1st and December 31st, 1961 in the Kenyan region of Africa. The record also reveals that the certificate was the only one issued for this specific type of arrival in the U.S. over a span of more than 18 months, among thousands from other parts of the world.”
If BO had been issued "statutory" U.S. citizenship, per the quote above, then that would be the basis for his eligibility for the previous two offices he held (Illinois House and U.S. Senate). Remember Alan Keyes was reported to have said in the Illinois Senate race debate with BO that BO wasn't a natural born U.S. citizen, and BO was reported to have replied "I'm not running for President."
So either BO isn't a U.S. citizen of any stripe and he was able to fake his way into office in the Illinois House and the U.S. Senate, or he provided his statutory proof of U.S. citizenship for those offices, but statutory citizenship would render him ineligible for the office of President (as Keyes is reported to have pointed out in the Senate race debate).
