Someone born outside the US of US parents can be a citizen. That is probably what you are thinking of. However, a child of alien parents, born in the US id a US citizen.
That's how it works.
I have a superior memory.
I know the person who had the booklet, I saw the booklet, and later, when his child was born he happily said:"NOW MY SON CAN BECOME THE PRESIDENT, IF HE SO CHOOSES TO RUN!".
I am NOT lying, I did NOT make any of this up, but I do NOT know IF this has been changed or deleted from the booklets that are handed out to study, or even IF it is a question on the test today; however, this LAW was in effect for Obama, Haley, Harris, etc. when they were born.
But Obama is a DEM, so he skated.
Wanna bet IF the Dems will allow someone to "skate" IF they don't fall into being a REAL NBC, if one such ever gets the GOP nomination?
