I don't know what I had for the first 31 years of my life. But it wasn't an official birth certificate. I know, because I took it down to the passport office to apply, and discovered it wasn't an official birth certificate. It was something you wave at the state official to get a copy of your birth certificate.

I have had to get several, since they have a bad habit of getting lost. I needed one when I applied for a passport. I needed one when I went for my first driver's license. I know I'm a natural born U.S. Citizen. I expect Mr. Obama is too.
