Obama having dual citizenship at birth doesn’t mean he isn’t a natural born citizen, I’m a natural born citizen who was also born with Irish citizenship (and I could get British if I wanted to fill out the paperwork), I’ve never been to either country and it hasn’t ever changed my U.S. citizenship status. You have to renounce your U.S. citizenship in order to lose it if you were born in the U.S.
You are most certainly a citizen, but the courts have never really defined "natural born citizen", except in dicta, which doesn't really count. It may mean "citizen at birth", but there is much evidence to indicate that it means a bit more than that. Of course the only time it matters is if the person wants to become President, otherwise, natural born or not, citizens all have the same rights, powers, and priveleges. Although there are some requirements for office based on being a citizen for some number of years. For example a Senator must have been a citizen for at least 9 years, but since they also have to be 30 years old, that's not a problem for any but recently naturalized folks.
I said "means", but what counts is what it meant in 1787 when the Constitution was written.
You are wrong about this. A Natural Born citizen is born on U.S. soil to two citizen parents. You can not have dual citizenship if both parents are U.S. citizens. If one parent is a citizen or neither are citizens but you are born on U.S. soil that makes you a Native Born citizen. Two different things
