Just out of morbid curiosity, now that we have sketchy documentation from Hawaii (mostly unverified), and ostensibly false information attributed to Kenya, why do we simply accept the birthday of Aug 4th?

I suggest April 1st as a good working hypothesis.
I'm kind of partial to July 24th - When I worked with the numbers on the pregnancy calculator at www.amazingpregnancy.com, it appears that Barack Obama would have been conceived on October 31 ;-)
Maybe this pic is not so far off the mark...
