There is numerous other bloggers that are posting about the Obama long form Birth Certificate is a forgery, based upon the layering and the linked additions being rotated 90 degress. However there is even a reason to doubt the authenticity of the document that has been posted.
The title of this article is correct. After
having completed a more thorough review of the relevant US Supreme Court cases
discussing the Constitution’s natural-born citizen clause, I have
discovered precedent which states that a natural-born citizen is a person
born in the jurisdiction of the US to parents who are citizens. Read that again.
I said precedent, not dicta. The precedent holds that Obama is not
eligible to be President of the United States.
