An intriguing, and quite unlikely, excuse... but maybe you can READ AND LEARN for a moment: The reason you provide is now moot. Why doesn't Obama save hundreds of thousands of dollars in current and future legal defense fees, and simply provide it now?
What does he have to gain by doing so? Think about it. Keeping the certificate from the public allows nutjobs to move in an marginalize the Conservative movement. The left gets to paint us as wackjobs and Obama looks like the victim.
He has absolutely nothing to gain by showing his Birth Certificate. If I were a marxist thug I'd do exactly the same thing.
Obama's handlers know that if they give their opponents the rope, they'll hang themselves.
This is Obamas Gramscian strategy designed to redirect the opposition down a blind alley.
