I think that you are right on the technical and legal points.
However, the appallingly ignorant American public simply will never recognize the difference between a citizen and a natural-born citizen if it gets down to the argument of where his father grew up.

I believe you are correct. It is not just the birth certificate issue. He has also hidden his college thesis, etc.
He has hidden his past relationships with a number of unsavory souls including William Ayers, Van Jones, we could name others. He is appointing people who are pushing an agenda-(Kevin Jennings) and he has participated in criminal activity with ACORN.
It is the whole picture, it is not just the birth certificate.
