It's a useless debate without that one piece of paper...so why exhaust yourself? It's all nuts if you ask me.
So? The short form COLB that he posted on the internet, physical copies of which he permitted reporters to inspect at his campaign headquarters, is just as valid for the purposes for proving he was born in the United States.
There are the birth announcements in two Honolulu papers. Both papers are on record that they got birth announcements directly from the Hawaii department of Health, so the birther claim that his granny could have phoned them in doesn't hold any water.
There's the fact that a family friend, who was his English teacher, remembers hearing of his birth in Hawaii when it happened.
There's the fact that his Kenyan relatives all confirm that he was in Kenya for the first time in the late 1970's.
There's his Kenyan step-grandmother, who is on record that she received notice of his birth in Hawaii via a letter from Obama Sr in 1961. And no, she never said he was born in Kenya, despite Berg's attempts to twist her words.
There's the sheer impluasibility that his pregnant mother would fly to Kenya in 1961. It's highly doubtful she could even afford it, nor is there any reason to believe her husband would want to take her to Kenya. Quite the opposite: we know Bambi's grandpa disapproved of BHO Sr.'s marraige to a white woman, and we also know he was hiding from Bambi's mother that he was bigamist. It just plain absurd to think either of them would want to go to Kenya in 1961.
Finally, there's the complete lack of any evidence he was born in Kenya.
Taken together, that's a moutain of evidence, and that's why no one outside the tinfoil hat crowd is questioning his birthplace.
