Even if the document were fraudulent, it would not matter. His birth in Hawaii has never been seriously contested, and he is therefore a natural-born citizen.
For those with TDS, it might be illuminating to note (and confirm) that Donald Trump NEVER claimed that Barry was not a citizen, not born in the U.S., or was born anyplace else. What Trump said publicly was that the many years that Obama allowed this minor "scandal" to continue when he could have stopped it immediately, says SOMETHING about his history that Obama does not want to come out.
It is similar to his academic records, when a 'C' student at Occidental College is able to transfer into Columbia - something that simply cannot happen. THey have very few slots for transfers and these are given to a very select few people. If Obama claimed to be from some shit-hole country in Africa, that might have put him at the top of the list, but we don't know, do we, how he got in.
