As I posted earlier on this thread, that law should never stand up to constitutional scrutiny if it is challenged -- because it makes it perfectly legal for Congress to reject electoral votes from one or more states even if there was never any dispute about the validity of those electoral votes. That is a blatant violation of the sovereignty of state governments, and has no basis in constitutional law. It's ludicrous to have a law on the books that allows (for example) California to lead an effort in Congress to disqualify the totally legitimate electoral votes of Texas.
