The fact that trump limits his attack to obama’s birth location rather than the broader “natural born citizen” question indicates trump is not fully versed in the subject. Also trump’s position is not as strong as it could be. Obama could have indeed been born in Hawaii but wants to hide something. So trump could be playing this a bit smarter by not boxing himself in.
There is a broader issue. If I need a birth certificate for my son to play baseball then why does the president get a pass?
He mentions “natural born citizen” in his CNN interview.

“Why doesn’t he show his birth certificate? The fact is, if he wasn’t born in this country, he shouldn’t be the president of the United States,” the billionaire developer said in a CNN interview that aired Sunday. The Constitution requires that the president be a “natural-born citizen.”
