Why doesnt Obama just show his longform Birth Certificate?

I really grow weary of the concpiracy theorys on Obama`s Birth certificate. Why doesnt he just show his Hospital generated birth certificate instead of some generic certificate of live birth that has the number all blacked out and is online only?? Just display the original hosppital one from hawaii. Now the New York TImes survey is saying that 58 percent of americans think he is from Hawaii that means 42 percebt dont think he was born here isnt this getting out of hand??
