Absolute Proof his father was not an American citizen.
His father's name is listed on the short-form COLB. So again, why do you need the long form, exactly?
Why? Again, he's admitted on hundreds of occasions that his father was a Kenyan student studying in the US. Do you think you're going to get him in court and he'll suddenly produce a long form birth certificate that shows it's someone else?
What you're arguing is not what it says on Obama's birth certificate, but what the constitutional definition of "natural born citizen" is. And that's something that no document of Obama's is going to define for you.
