The answer would be yes, I would argue, because the US constitution places the responsibility for the manner of choosing electors in the state legislatures. The legislatures delegate that through state law to the voters, voting under the laws established by the state [and in accord with federal election law which I believe derives from the equal protection clause - all voters have to be treated equally].
If the law is not followed, then the legislature as the supervening authority has the right to choose the electors themselves.
Right. And the "fact checks" out there claiming that the state legislatures have no such right leave out the vital matter that they do have such a right IF they find that the elections have been in VIOLATION OF STATE LAW.
