The long form REAL birth certificate has all this information. Obama has fought the long-form certificate coming out so logically the answer is WHY? It seems logical to assume that there's some incriminating detail on it (parents not married, name was different then, Muslim relgion listed...any number of things).
One of the docs posted by Obama's lackies that is in dispute is called a "Certification of Live Birth"....NOT a "Certificate of Live Birth". You need glasses. Here, I'll post it nice and big for you. Read slowly and carefully.
