One of summary statements in the report is critically important:
If, in 1961, 17 year old Ann Dunham gave birth to a child on foreign soil whose father was not an American citizen, then the Immigration and Nationality Act at that time denied Barack Obama any right to American citizenship of any kind. Therefore if at the time of his birth Obama was ineligible for American citizenship of any kind, then he cannot be a “natural-born citizen”. This is true even if the Immigration and Nationality Act was changed 33 years after he was born. Even if the law was retroactively changed to grant citizenship (but not “natural-born” citizenship) to some of those who had at birth been denied it. If a person is not at the time of his birth an American citizen, he cannot be a natural-born citizen. Therefore, that person is ineligible under Article II, Section1 for the Office of President of the United States.
There is no possibility whatsoever that Obama is a natural born citizen and therefore qualified to be president.
