If the law defining what constitutes “natural born” changed in 1986, and Obama was born in 1961. He wasn’t “natural born”, when he was born. If he wasn’t born in Hawaii, he’s not eligible to be President.

Indeed, in 1961 the Supreme Court of the United States specifically ruled that a person who was born in a foreign country to a mother who was a citizen and a father who was not a citizen was NOT a Natural Born Citizen.

Yes. Then, in 1986, legislation was passed to address that, putting them in the classification of Citizen by Birth. It is unclear how the 1961 decision would apply, but IANAL. :-)
