The case law on persons born-abroad is very clear, completely consistent, and says that all citizens born abroad are naturalized citizens.
The case law on citizenship of persons born in the US superficially leads to the conclusion that they are qualified for the presidency.
Rubio's parents were Cuban citizens who, at the time he was born, intended to return to Cuba. Rubio was born a dual citizen, and while the case law isn't as clear as it is for persons born abraod, the case law strongly suggests that a person born a dual citizen is not qualified for the presidency. Kawakita v. United States, 343 U.S. 717 (1952)
Appreciate your scholarship on this issue.
“a person born a dual citizen is not qualified for the presidency”
So that would rule out Cruz, too. Another dual citizenship. Our president needs to be 100% American citizen. How hard is that, really?
