I doubt there's anything Obama could do to stop this guy's self-destructive path. If he released his birth documents, the defense would just move to a more nuanced Constitutional argument, as many birthers have done.
Oh, that little bitty nuanced thing about his dad being a British citizen? Or do you mean that nuanced fact about his mother not being old enough to pass on citizenship to Obama? Or perhaps it would concern his own Indonesian citizenship and his possible lack of ANY type of U.S. citizenship? The list goes on. So, yeah, I guess you’re right, in for a penny, in for a pound. That’s us birthers. We just love getting all nuanced up when it comes to the Constitution. Not because it should be followed or anything.
