Has he been revealed as a fool? Or vindicated by getting the president to produce the full document? A little of both, don't you think? But from the press's point of view, we must surely be glad to have more data, rather than less, no?
Here, by the way, courtesy of TNC, are the legal rules for publicly producing such a detailed document:
The department shall not permit inspection of public health statistics records, or issue a certified copy of any such record or part thereof, unless it is satisfied that the applicant has a direct and tangible interest in the record.
As TNC notes, "direct and tangible interest" means the registrant, an agent of the registrant, their parents, spouse and some others. So Obama had every reason and capacity as both the person whose birth certificate is on record, let alone as president of the US, to have done this months ago. But he decided to play rope-a-dope instead.
