Actually I wasn't born in this country and I only have a copy of my birth certificate, which took a lot of work to get. When I attended school computers weren't used for filing yet I wouldn't be surprised if my files were missing. My school did not have a copy of my birth certificate since I did not receive one until I was 18. In fact my elementary school does not exist now. Things were also run a lot looser back then. Obama may have attended for a month and then his parents pulled him out. The school secretary may have just thrown out the file.
It wasn't until John Kerry ran for office that a lot of his past came out. For one he wasn't Irish as his senate profile claimed. His military service was very brief, this was not known before. His grades in college were very mediocre. I don't think John Kerry's elementary school transcripts were released.
"Actually I wasn't born in this country"...maybe you are making my case and it is more than likely nobama fits in the same category. you say you don't have a Birth Certificate from the USA - since you weren't born here, if you had been born in the USA you would more than likely have one...my parents are in their late 70s and both have an original BC.
