At this juncture, no reasonable person could come to any other conclusion than obama, by ignoring all request for information and all the money spent squashing legal challenges, is hiding something. if that makes one a birther, then so be it.
It would be a very simple matter to put this to rest and make birthers look dumb in the process, if in fact he is a natural born citizen.
If he is an alien he is unqualified to be POTUS. If he is a natural-born citizen we have a right to see his college and law school records to see if he got financial aid meant only for foreigners. No big deal to respond.
You know he's not. Unless he lied about who his father was. He gets to tell "Grandma Sarah" (one of his grandfather's other wives) about that. She will not be amused.
But since she has said that he's like his father returned in his mannerisms and other ways he probably wasn't lying. He certainly doesn't look like his father, but many people don't, and he does look a lot like his white grandfather, other than coloration and a slightly broader nose.
But, if he wasn't lying, and his father was the non US Citizen, Barrach Hussein Obama, student from Kenya, he cannot possibly be a natural born citizen, even if he was born on Diamond Head or on the lip of the Punch Bowl Crater. (Kapioloni hospital, which is where the posted COLB says he was born, is about a mile from the crater)
