If Obama was a stand up cool dude; he would have produced the original already. But this doesn’t appear to be the case. Instead Obama appears to be a weak coward with nothing going for him. I suspect that is the real story of his life. People who have to hide things and lie about their lives are the real losers.
If Obama continues to refuse to release his original birth certificate, a reasonable person might assume he was not born in a Hawaiian hospital or at home with assistance of a doctor or midwife.
This is especially true because if Obama was born in a foreign land, his family had a compelling reason to lie about it, given the prestige and benefits of American citizenship.
If at birth, Obama was ineligible for American citizenship of any kind, he cannot be "natural-born." If a person is not at the time of his birth an American citizen, he cannot be a natural-born citizen and is ineligible for the Presidency.
