Missing birth certificate

Representative Roy Blunt of Missouri said:

What I don't know is why the President can't produce a birth certificate. I don't know anybody else that can't produce one. And I think that's a legitimate question. No health records, no birth certificate ...

The "birther" conspiracy is a batshit crazy conspiracy theory that is getting far more attention than it deserves, and here Roy Blunt is saying something incredibly ironic to legitimize a fringe claim. Googling "Barack Obama birth certificate" gives a news article right on the top which shows a copy of Barack Obama's birth certificate. Compare this to googling "Roy Blunt birth certificate", which shows no sign of Roy Blunt's birth certificate for ten pages. Is Roy Blunt an American citizen, much less a natural-born American?

What I don't know is why Representative Roy Blunt can't produce a birth certificate. I don't know anybody else that can't produce one. And I think that's a legitimate question. No health records, no birth certificate ...
