There were very good reasons for the founders to exclude the children of foreign nationals from the office of President.
Illegal alien children with no allegiance or loyalty to America are not natural born citizens.
They may be citizens by a misinterpretation of the 14th, but they are not eligible to be President.
PreambleWe the People gave ourselves the power to directly elect our representatives to the House of Representatives in the United States Congress. If you cannot vote for a Representative, then you are NOT We the People.We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
Article I Section 2
The House of Representatives shall be composed of members chosen every second year by the people of the several states...
We the People "...ordain[ed] and establish[ed] this Constitution... in Order to... secure the Blessings of Liberty to ourselves and our Posterity." It is clear that Barack Obama's father could not vote for the House of Representatives, therefore he was not "We the People." This means that Obama Jr. was not the "Posterity" of "We the People."
The "natural born citizen" clause was meant to secure the presidency. The presidency has the tighter requirement of "natural born citizen" in contrast to Congress which only required "citizen." In other words, "citizen" equaled "We the People," while "natural born citizen" equaled "Posterity of We the People."
Barack Obama Jr. is not the Posterity of We the People, therefore he is not a natural born citizen. He is what Thomas Paine called "half a foreigner" in chapter 4 of The Rights of Man (1791), two years after the ratification of the Constitution.
