Well, if that's his brilliant scheme, then when's he going to come out and mock us? He's going on two years in office, and he's done nothing but evade this issue completely.
I remember this theory from early on in the controversy, and it made sense at the time, but it's now two years on, and he's remained silent. If he was going to spring a trap on the birthers, he would have done so by now.
That is what its hiding in my opinion. He was listed as British under his fathers name, under his fathers heritage.
But that's common knowledge, and has never been denied by Obama or his camp. It's in his book, and is a central plank of his personal narrative. He can't be "hiding" that information on an unreleased birth certificate.
No, he's hiding something else. Something that he'd rather die than admit to. Something that will destroy him, both politically, and personally.
Knowing Obama to be the serial liar that he is, it's probably a whole combination of lies, which the bc would expose. This is why he's locked down every public record that he has. His lies run to every sector of his past, and he cannot allow anyone to see what an abject liar he really is.
He doesn't need to spring a trap -- just sit back and let the circus go on, basking in the knowledge that it makes all of his opponents look a bit clownish.
