Do you think BO was DEFINITELY born in the United States?

Yes, he was definitely born in the USA. It would have been impossible to conceal this fact prior to the election.

But the foreign-born clause in the Constitution is frankly idiotic. I was 2 years old when I immigrated to the USA and lived there for 16 years, I consider myself to be more American than any other nationality, so why shouldn't a foreign-born citizen be allowed to run for President?
Technically our first few Presidents were foreign-born, they were born in the British Empire, we just gave the land a new name and new laws and fought a war for it to change, but that doesn't change where they were born.
