Obama’s roots [the condition of belonging to a particular place or group by virtue of social or ethnic or cultural lineage] make him ineligible as President of the United States.
When was the United States Constitution amended to allow anyone other then a ‘Natural Born Citizen’ of the United States eligible [the right or privilege] to be President of the United States per the United States Constitution Art 2 Sec 1.
“No person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President; neither shall any Person be eligible to that Office who shall not have attained to the Age of thirty-five Years, and been fourteen Years a Resident within the United States.”
The meaning is clear, that the roots of both parents being from the same country or nation. Barack Abdallah Husein Obama, born of a foreign father who does not have American roots, was never a United States Citizen, regardless of his mother, fails the ‘Natural Born Citizen’ requirement of the United States Constitution.
