Even if it is real (doubtful) it confirms Barack Sr., a British Subject, as 0bammy’s daddy, making Hussein a dual citizen - NOT “natural born”.
That Obama's father was never a citizen was never a secret. It was in Obama's autobiographies; everyone knew it.
But during the primary elections, none of Obama's opponents claimed that that made him ineligible to run. During the general election campaign, McCain and Palin never claimed that that made Obama ineligible. During that campaign, no conservative legal organization (Thomas Moore Center, ACLJ, Judicial Watch, etc.) ever filed a challenge to Obama's eligibility. No law professor wrote an op-ed article questioning Obama's eligibility.
After the election, no member of the electoral college questioned Obama's eligibility. When Vice President Cheney certified the electoral votes before a joint session of Congress, not one member of the House or Senate raised any objection to Obama's eligibility. Chief Justice Roberts swore Obama into office without questioning his eligibility.
In the past, we elected a Vice President, Spiro Agnew (the VP is required by the Constitution to have the same qualifications as the President), whose father wasn't a citizen. No one at the time claimed that he wasn't qualified to hold office.
At this point, the odds of any court in the U.S. defining "natural born citizen" to mean anything but a citizen who is born, not naturalized, is exactly zero.
