"Jus sanguinis" involves who your parents were and their citizenship.
There was a historical argument over "natural born" and presidential candidates. One in particular, but in this century John McCain, Barack Obama & now Kamala Harris have all been nominees and at least one served as POTUS. It's a dead issue that would require a constitutional change to clarify the situation and that'll never happen.
I think the Left stirred it up over Kamala to try to connect her with Obama. They'll paint her as the best of both worlds: Hillary & Barack with only senile old Joe standing in her way.
We need to be asking who would Kamala pick as her VP. My guess is not a white male.
My guess is fellow imbecile Cory (lazy eye) Booker.
My guess would be Eric Holder to ensure their crimes remain buried.
