@servelan The problem is that the Court found the presidential election to be a federal procedure so this wasn’t just a state regulating private action since the feds had not, but rather this was seen a state regulating the federal government itself.
I don’t fully agree that a presidential election is a federal process, but given that it is, as the Court found, it’s a little more understandable.
It would be like Texas proposing to regulate some practice in the EPA just because Congress had not passed a law related to that specific practice.
Or, this analogy is a little more complicated, but Texas proposing to regulate the federal border patrol. It would be disallowed for the same reason, and that is certainly current events at this point.
