Barack Obama is not a legal U.S. natural-born citizen according to the law on the books at the time of his birth, which falls between December 24, 1952, to November 13, 1986. Federal Law requires that the office of President requires a natural-born citizen if the child was not born to two U.S. Citizen parents. This is what exempts John McCain, though he was born in the US Panama Canal Zone.US Law very clearly states: '. . . If only one parent is a U.S. Citizen at the time of one's birth, that parent must have resided in the United States for minimum ten years, five of which must be after the age of 16.' Barack Obama's father was not a U.S. Citizen is a fact.
Obama's mother was only 18 when Obama was born. This means even though she had been a U.S. Citizen for 10 years, (or citizen of Hawaii being a territory), his mother fails the test for at-least-5-years- prior-to Barack Obama's birth, but-after-age-16.
In essence, Mother alone is not old enough to qualify her son for automatic U.S. Citizenship. At most, 2 years elapsed from his mother turning 16 to the time of Barack Obama's birth when she was 18. His mother would have needed to have been 16 + 5 = 21 years old at the time of Barack Obama's birth for him to be a natural-born citizen. Barack Obama was already 3 years old at the time his mother would have needed to be to allow him natural citizenship from his only U.S. Citizen parent. Obama should have been naturalized as a citizen . . but that would disqualify him from holding the office.
The Constitution clearly declares: Naturalized citizens are ineligible to hold the office of President. Though Barack Obama was sent back to Hawaii at age 10, any other information does not matter because his mother is the one who must fulfill the requirement to be a U.S. Citzen for 10 years prior to his birth on August 4, 1961, with 5 of those years being after age 16.
That is one possibility. But if born in Hawaii, that would be moot.
Most clear explanation I’ve read.
The law even more clearly states: "The following shall be nationals and citizens of the United States at birth: (a) a person born in the United States, and subject to the jurisdiction thereof;" If Obama was born in Hawaii, as claimed, then his mother could have been any age and he's still a natural born U.S. citizen. If he wasn't born in the U.S. then where's your evidence?
