No, it “plainly means” one who is born as a citizen. As opposed to someone who, later in life, goes through a “natiralization” process.
Do you mean to say that an ambassador’s child born in anothet country can not become president?
Obviously a person born a US citizen is eligible. This was discussed regarding McCain who was born in the Panama Canal Zone. I thought Cruz was born a Canadian, obviously I was wrong. If he was born a US citizen he is eligible.
Some of these people think if George and Martha Washington crossed into Canada and she gave birth, their child would be rendered ineligible. Ridiculous.
