I'm not lawyer but that sounds like a legitimate complaint.This bill may be in trouble if the states fight it legally. IS it constitutional or not? Because it sounds like it is telling the states how to run an election when that power is specifically reserved for state legislatures.
Except the law as far as I know, restricts states from doing certain things, rather than telling them they have to do other things.
Again, I'm no lawyer so I have no idea how that will play out.
