The website says the publication “of such a blatantly fake document about something so basic as the birthplace of Mr. Obama, should raise great concern about the suitability of the person who is holding the reigns on the most powerful country of the World.”
Barack Obama's actions while in office and his long list of well-established and indisputable anti-American associations are more than enough to raise great concern about his suitability.
FWIW, I have no doubt that he was born in the US.
