If it is, indeed, the opinion of the government of the USA and our Constitution, why has it never been enforced? In fact, two people have been elected president despite having only one American citizen parent.
And WHY are you completely ignoring the FACT that twee Teddykins, flat out stated, when he was running for his Senate seat, that a NBC was a person born on AMERICAN soil, whose mother AND father were both citizens of the USA, at the time of said child's birth ?
And FYI....this is the info that is in the study guides, printed by OUR government, handed out to all those who are LEGALLY trying to become citizens of this nation and who are studying for the exam. Also, I know for a certitude, that this info was given to dear Tedddykin's crazy father, when he was studying to become a citizen in 2006!
