So then that boils down to the real question. If laws are made at the state level and state election officials can violate them, what the point of SCOTUS? The law is the law they are final arbitors of law. Doesn’t have an “* void if it concerns elections.” SCOTUS can find gay marrage rights that dont exist. Baby killing rights when it doesn’t exist, but can be bothered with violations of Constitutional protected states legislature rights to make election law when it does exist? That dog dont hunt.
The SCOTUS is only the final arbiter of Federal law.
And even then, most Federal laws are blatantly unconstitutional in that they violate the explicit terms of the Tenth Amendment.
