I read it in a pamphlet.
It is called the Constitution of the United States.
Perhaps you've heard of it.
Article II... Section 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."
Obama, if his father is of Kenyan descent is not eligible to be President unless of course is father was more than 240 years old.
That really doesn’t answer the question that was asked?
