“Section 1. All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside. No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.”
You failed to notice Bingham called them Citizens of the United States, NOT Natural Born Citizens.
Read it again.
And Ankeny citing Wong didn't differentiate between the two. Ankeny is, so far, the only court case to render an opinion on Obama's eligibility as far as the "2 citizen parents" is concerned.
Do you see Ankeny overturned anytime soon? I don't.
