You have to look at the born out of wedlock to a US citizen mother law which is different.

It is based on how the UK would have viewed his birth with an out of wedlock birth. It might hinge on whether Sr was listed on the birth certificate and presumed father or whether they had to be legally married in the eyes of the UK law.
If Obama born in Kenya- then he would have UK citizenship.
If born in Kenya out of wedlock -then he would have US citizenship.
If born in Kenya to legally married Sr and Ann - not US citizen.
If born in US out of wedlock - not sure on UK citizenship.
