Though I question his citizenship I only do so because of the money he has thrown at keeping the birth certificate debate out of courts.  But here is some information that is interesting in the debate.

Natural Born Citizen

Article II-Section I-Clause 5 of the US Constitution requires that ONLY a "natural born citizen" hold the office of President. It's no secret what they meant or why that clause exists. It is a matter of national security.

Lets not play any games here, too many games have been played with this phrase already. It's a very simple term that anyone with a dictionary can figure out.

Not just any ole "citizen,"

Not Native "belonging to a particular place by birth"

Not Naturalized - "to confer the rights of a national on; especially : to admit to citizenship" (as with an immigrant)

But NATURAL - "Pertaining to nature; produced or effected by nature, or by the laws of growth, formation or motion impressed on bodies or beings by divine power."

The US Senate got it exactly right in 2008 in their unanimous resolution proclaiming John McCain a "natural born citizen" of the Unites States of America, based upon the well-known fact that BOTH of his parents were indeed legal citizens of the United States at the time of John's birth. In other words, by "divine power" and the "laws of growth," "produced by nature" of the fact that his parents were US citizens, so was John McCain, by birth right via natural ancestry.

However, no such Senate resolution concerning Barack Obama exists, and the standard applied to John McCain is NOT being applied to Barack Obama.

The Birth Certificate

Obama supporters like Snopes and FactCheck claim to have a copy of Obama's birth certificate, but they do NOT. I challenge any reader of this column to send me a certified copy of Obama's actual birth certificate and I will gladly disclose it to the public along with a retraction of this statement.

I won't get one, because no such document has ever been released by Obama. End of story!

Officials in Hawaii have issued their "opinion" that Obama is a "natural born citizen" of the United States. But they have thus far refused to make public the documents used to arrive at that opinion, and until they do so, their "opinion" is nothing more than inadmissible hearsay from a third party NOT present at the time of Obama's birth, and they are therefore, unable to support such a claim.

Not one, but THREE different COLBs, (Certification of Live Birth, not to be confused with an actual birth certificate) have been posted online by Team Obama, Snopes and FactCheck. But none of the three contain any verifiable information necessary to vet the documents and since three have been offered, all must be treated as forgeries until one of them can be authenticated.

Some "birthers" believe Obama was born in Kenya, not Hawaii. That's because Obama's Kenyan relatives have stated under oath, that they were present at Obama's birth in Kenya.

But where he was born isn't so important. The fact that he was born to a father who was at no time a citizen of the United States, is the problem. On this basis alone, Obama is NOT a "natural born citizen" of the United States and that makes him an "unconstitutional president" at best!

Proof of Constitutional Standing

Other than the three different COLBs posted online by Obama, Snopes and FactCheck, Obama has offered NO other proof of legal US citizenship, much less "natural born" status as required by Article II of the Constitution. NONE! If you think I'm wrong, send me the proof you have!

We know that he traveled to Pakistan, among other places in the Middle East, during his college years, and that he did NOT hold a US passport at that time. We know that he received his first US passport as a "diplomat," while he was a state senator in Illinois, which also allowed him to bypass the normal process of getting a US passport.

But because he will not open up his records, we do NOT know what passport he traveled on during those college trips to the Middle East.

We know he attended three of the most expensive colleges in the United States. But we do NOT know how he was able to pay his tuition without any job, why he changed schools, or why former Black Panther Godfather Dr. Khalid al-Mansour (aka Donald Warden, Saudi Royal Family front man) and New York Panther Percy Sutton, helped him into Harvard.

Bottom line, Obama is one great big secret mystery!
