The law is whatever some dumb-a$$ judge says it is.
But there is a requirement that the nominees for President and Vice President be from different states. It might be too much of a burden for the Clintons to admit that they do not live in the same state. Kind of ruins that "happy marriage" myth...
“... there is a requirement that the nominees for President and Vice-President be from different states.”
IIRC, the Constitution says that a state’s electors (to the Electoral College) cannot vote for candidates for President *and* Vice-President if they are *both* from that state. As a practical matter, to prevent the possibility of a split Presidency and Vice-Presidency and for geographical balance, nominees for President and Vice-President historically have been from different states.
