List of U.S. Presidents – and their Constitutional Eligibility under the U.S. Constitution’s Article II, Section 1 “Grandfather Clause (GFC)” or the “Natural Born Citizen (NBC) Clause”, or were they seated unconstitutionally due to Election Fraud. Under the Grandfather Clause the person must have been a Citizen of the United States at the time of the adoption of the U.S. Constitution. Under the Natural Born Citizen (NBC) Clause the person must have been born in the USA to parents who were born Citizens of the United States when the child was born. Under the NBC clause it does not matter if the parents were foreign born but only that they both be U.S. Citizens (either born or naturalized) when the child is born in the USA. Both Chester Arthur and Barack Obama were unconstitutionally seated due to Election Fraud and their lying about their respective nativity stories and hiding and destroying their personal early life records. It has been recently discovered that despite the fact the Chester Arthur’s father ultimately was a U.S. Citizen, he did not naturalize until after his son Chester Arthur was born. Obama’s father was never a U.S. Citizen, never intended to be, was not even an immigrant to the USA nor was he even a permanent resident. Obama’s father was a foreign national sojourning in the USA to attend college. Obama’s father was a British Subject and at birth Obama was also a British Subject governed by the British Nationality Act of 1948. Obama was thus not a “natural born Citizen” of the United States and is constitutionally ineligible to be President and Commander in Chief of our Military.
