[Barry Goldwater]

You got it! Good one. The United States didn't even exist when the first few presidents were born, so how could they be born in the US?

Your reply is great. Goldwater wasn't born in the US either. Excellent and thanks!

Goldwater wasn't born in the US either.

Although the Arizona Territory was not a state at the time of Barry Goldwater's birth, it was part of the United States and therefore Barry Goldwater was a natural born U.S. citizen and eligible for the Presidency.
