IIRC, Goldwater was born in a US territory that later became Arizona. Also, old-man Romney was born in Mexico.
Sorry, I accidentally hit mail reply instead of posting.
George Romney was never a party nominee. If you are going to bring up Barry Goldwater for being born in a territory, also look at Andrew Jackson, there was some question there as to which state or territory he was born in.
Cruz is a big question mark that needs to be settled by the courts as soon as possible. I personally think giving Cruz a pass weakens the Constitution.
Ah, I see wisdom has found this thread!
