That is incorrect. An anchor baby is clearly eligible to be President. “Natural Born US Citizen”. No question.
That’s absurd
You do agree that an anchor baby is a citizen. If you don’t agree with that then you are ignorant. Since the Anchor Baby is a citizen , then under the Constitutional requirements for eligibility to be President ,the only other issue ( besides age) is was the citizen born on US soil. To conclude otherwise is indeed absurd.
