We've gone round on this before, so I'll just state it for the record - the Constitution states the president must be certifed as meeting qualifications which include being natural born. To argue that an exact process for carrying this out is not specified is a specious argument - an example is statutes, which require regulations for implementation. Not implementing a statute does not mean Congress fell short on the statute, it just means that someone didn't carry out their regulatory job. In short, this is a mandamus issue against those designated by the Constitution to verify the president - in Obama's case it was Pelosi and, I believe, Cheney, who simply failed to perform their duties. The States have no input into this Constitutionally designated process.

And I'll state it for the record, also like you (once again) -- that Obama has qualified the same way all the other and prior candidates have qualified.
The Constitution says that he must be qualified per the Constitution, not that he must be "certified" ... (and that's the loophole, doncha know... :-) ...).
He must be...
He has qualified in the same way any candidate has qualified -- in that they have all signed a sworn statement that they meet those qualifications. That's all they have ever had to do...
Hence, that's why state laws are needed to require a candidate to produce his birth certificate or else he cannot be on the ballot in that state (because showing a birth certificate is not a legal requirement right now, or else, if it was, it would have been ordered by a court a long time ago... :-) ...).
