Law Professor Derek Muller has this article about qualifications to be president and how challenges to ballot access based on failure to meet qualifications could ever arise. Thanks to Rick Hasen for the link.
UPDATE: here is a very thorough and clear essay in The Atlantic by Law Professor Bryan A. Garner. Thanks to HowAppealing for that link.
NBC = AT birth ALLEGIANCE to a regime via father.
Naturalization = AFTER birth change of ALLEGIANCE to a regime.
Place of birth means ZERO.
Basic NATION-STATE ALLEGIANCE stuff.
Think also things like ship wrecks of highly pregnant foreign women and invasions / occupations of areas during wars.
i.e. the Japanese father kids (i.e. rapist cases) born in occupied USA areas during World War II — were obviously NOT U.S.A. citizens.
How many States have court cases stopping UN-qualified candidates for Federal, State/local offices from getting on ballots ???
What century will the SCOTUS hacks get some brains ???
