You are wrong sir:
Here is the law, chapter and verse:
The U.S. Immigration Law that covers the issue of children born abroad to 1 citizen and 1 alien.
http://library.uwb.edu/guides/USimmigration/66%20stat%20163.pdf
the McCarran-Walter Act, the Immigration and Nationality Act of 1952
Public law 82-414 Chapter 1 Section 301 (7)
This applies to Obozo (it was the law at the time of his birth), assuming he is the son of Barrack H. Obama, Sr. and that he was born abroad.
If born abroad with the stated father, he is not even a U.S. Citizen.....
If he was born in the U.S. he would be a citizen by birth, but not a “natural born” citizen.
