As you very well know, that has already been proven and ironically by the imposter himself when he publicly announced to the world that he’s not a natural born citizen but rather a native citizen with allegiances and loyalties to the foreign governments of Great Britain and Kenya.
Except that your definition of natural-born citizen is not supported by the Constitution, federal law, or any Supreme Court decision. It is an opinion of what natural-born citizen means, and nothing else.

Listen asshat, it’s clear to many that natural means no divided loyalties which that mud dog clearly has.
And it's clear to others that we operate on the Constitution and the rule of law, not theories pulled from that part of your anatomy where you head usually resides. Now, point out the clause in the Constitution, the federal law, or the Supreme Court decision which clearly states that natural-born citizen is defined how you say it is and we can all go home. Until then, it's still your opinion fueled by God knows what.
