Well we all know by his own accounts in his books, that he indeed moved to Indonesia when he was 6, and if my information is correct, Indonesia did not allow dual citizenship at that time (60's & 70's), which would mean that he would have had to have been an Indonesian citizenship and denounce his US Citizenship.
As for contacting Hannity, that is a very good idea, I will start on an email to him immediately.
I also read a post on a blog that someone had done some research regarding a Kenyan birth certificate for Obama, which (and this is just read-say LOL) had been sealed. My thoughts are, why would a record be sealed if the said record never existed.
