It will be revealed. That's for sure.
I think if the reason for the hiding the birth certificate was because of who his father is it it may take a little more time to be revealed than if it because of the place of birth.
Obama's a celebrity overseas. Celebrity mean $$$. Eventually (if he was not born in USA) a poor village will be wanting to brag. Especially once Obama's been re-elected. They know he cannot run again. At some point during his second term or soon afterwards it will be known. The village knows it will be a tourist attraction. That means money and lots of it. And all of this will happen without investigators. If they get greedy and impatient they just may spill the beans while he's still in his second term. What happens from that point I have no idea.
We will certainly look like fools to the world. It WILL not be pretty.
