Hell lady, you can be a natural born citizen even if your mother has no idea who your father was. The 14th Amendment makes that very clear. FYI, there are plenty of babies born these days with NO FATHER on the birth certificate at all.
Obama may not know who is REAL father is..but the purported information to this day is that Obama SR is the father and he was a UK citizen.
show me the case that clearly outlines the same exact conditions as Obama. I would like to see it.
