They have been careful not to use the word “birth certificate”. They refer consistently to “vital records”.
The words “natural born” have never appeared on any citizen's birth documents since the creation of our Republic. ( I'd bet my 401K on that).
And a physician has NO authority, experience, or education to declare anyone a natural born citizen. She has no access to many of Obama’s adult records that would be needed to make this determination. Neither does anyone else in an official capacity in Hawaii!
Their pronouncements are carefully worded obfuscations designed to mislead without actually lying.
