Interesting reader post from The Economist article:
The election may be called off next week if Senator Obama is not able to produce for a court the "long-form" birth certificate proving that he was actually born in Hawaii. While this seems quite unlikely, you can read the court filing for yourself
here. More than likely, this is all just a rumor. Some however might be interested in the court filing.
I read it and it is simple enough. It alleges that Obama was born in Kenya, that the airline would not let his mother return to Hawaii because her pregnancy was too advanced. If she returned shortly after giving birth she could have then registered him in Hawaii, and he would have a "short form" birth certificate.
It asks for three documents that if released to the court, would prove that Obama was born in Hawaii. There is no good reason for the judge to deny this request, Obama will be required to prove where he was born. If he was born in Kenya, he cannot be president. If he cannot prove that he was really born in Hawaii, he cannot be President. Everyone born in a hospital in Hawaii can prove this.
If the airline really did refuse her flight, then the election is now over. The lawyer involved is a close ally of Hillary Clinton, who would presumably replace Obama.
