(1)Only two Presidents have not been "Natural Born Citizens," as the term is traditionally applied. Chester A. Arthur, who it has now been established, lied his ass off about it. and BO/BS.
(2)BO/BS claims "Birth in Hawaii." That's unproven, but entirely possible. He has never personally claimed "Natural Born Citizen"-ship, because that's impossible.
There are for 2 reasons for this strategy:
(a)Rather than flat-out lie about it as Chester Arthur did, he has paid others to make the claim of eligibility for him
(b)His method has relied on clouds of legal "Pixie Dust," some provided by Team BO/BS, much more provided by a federal judiciary that dodges the obvious constitutional issues through their quite understandable wish to stay out of electoral politics, which they insist is the province of another co-equal branch, the Legislative, and therefore none of their business!
(3) I refer to the present resident of 1600 Pennsylvania Ave. Washington, D.C. as "BO/BS," because we have no idea what the man's legal name is. Upon adoption, his legal name would have had to be changed by court order on an amended BC. It would require a court order to legally change it back. Never happened. In fact, because we do not have the amended BC, we don't even really know what that adoptive legal name was (IS actually)! BO/BS has been caught in his lie to the Illinois Bar, to which he DENIED EVER having used another name.
Two people have come forward to shout that "The Emperor has no clothes!"
(1) Lt. Col. Lakin, who is in prison for it
(2) The Donald Trump, who is on TV with it.
