Barack Obama was definitely, 100% a natural-born citizen of the United States. See this 1952 bill:

“Sec. 301. [8 U.S.C. 1401] 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;
...
(g) a person born outside the geographical limits of the United States and its outlying possessions of parents one of whom is an alien, and the other a citizen of the United States who, prior to the birth of such person, was physically present in the United States or its outlying possessions for a period or periods totaling not less than five years, at least two of which were after attaining the age of fourteen years:”

Barack was born in Honolulu, Hawaii but even if he was born outside the USA, he was a natural-born citizen via his mother.

No, he definitely was not, or he wouldn't have asked McCaskill to inject wording helpful to him in her McCain resolution which he wrote, but got her (also) frosh butt to author.

Hmmmmm...no. That law came into effect in 1986 to present and does not apply to Obama. As you know, Obama was born in the early 1960s.

Barack was born in Honolulu, Hawaii but even if he was born outside the USA, he was a natural-born citizen via his mother.

I'll reserve my judgment on the type of citizenship Obama has until I see sufficient evidence.

How old was his mother at his birth?

This is not correct. Mother has to have 5 years past the age of 16 not two.
