To be sure. HOWEVER, their opinions are considerably more authoritative than YOUR opinion.<quoted text>
And all of those opinions were written after our Constitution was written and are, again, nothing more than an opinion.
The opinions that count are those of the Electoral College, not one of whose members changed their votes to vote against Obama either in the 2008 or 2012 elections (and frequently one or two Electors have voted differently than the votes in their states. ALSO the US Congress, which confirmed Obama's election UNANIMOUSLY twice. ALSO the Chief Justice of the USA, who swore in Obama several times.
And the US Supreme Court, which on October 1 of last year rejected appeals to the Farrar case in Georgia, which had ruled that EVERY child born in the USA is a Natural Born US Citizen. By rejecting the appeal, the US Supreme Court allowed the ruling of the lower court (and nine other state and federal appeals courts which had all ruled the same way) to STAND.
