But the current Electoral Act provides for the Congress to object to the slate of Electors “selected” by illegal acts under their own State Constitutions.

This is why the current Electoral Act is almost certainly unconstitutional. If Congress could reject electors from a state (presuming there are no competing electors submitted for that state), then you have basically turned the U.S. into a parliamentary government where the executive branch leader is selected by Congress. You’d have Chuck Schumer and Nancy Pelosi objecting to Wyoming’s three electors (for example) because one dude from a Shoshone Indian reservation claims he wasn’t able to vote.

no. again the objection was based around state legislators getting a chance to over see the rules. Which other legislators attempting to give them that chance.
