I have not been tracking the Obamanation birth certificate issue, but the democrats seem to have released a copy, not the original.
There are clearly things in the original that Obama DOES NOT WANT US TO KNOW!
That's a possibility, but more likely that Obama wasn't born in Hawaii at all, so there is no bona fide Hawaii birth certificate for him in existence - even though his "official" bio claims that he was born in Honolulu. There have been whispers that he was born in a foreign country (Kenya or possibly Canada), which would make him constitutionally ineligible to serve as POTUS, since, in that event, he would not be a "natural born citizen."
