The appointment of electors is a delegated right granted to the states by the Constitution and while that right can be amended( i.e.12th ) it cannot be amended without Congressional approval NOR in any manner that changes the overall purpose of the presidential election system.
The overall purpose of the presidential election system is to elect a President. The rule change Nevada proposed would not change that.
The question, which you are unable to articulate, would be if the courts see this rule change as
only an end run around the electoral college. And even if they did, this would be a textbook case of how a deeper interpretation of the Constitution needs to come to play to make a decision vs. some literal reading of the words written in the document (which you erroneously seem to think supports your case.)
The original purpose of the EC was a buffer against the provincial and misinformed masses. The Electors were originally able to vote for whoever they wanted. Only later did it become customary for those electors to vote for the first past the post winner of the statewide popular vote, making the voting process itself pure formality (for all but two states anyway.)
So what is it for now? I fully understand the argument that the EC supports smaller states who normally would get no attention in a nationwide race. No, I don’t agree with this argument, and think in practice it now slices the other way, where New York and California and Texas are ignored while swing states wield all the power. But what is to prevent a state from voluntarily putting itself in that position? Why can’t they say “We will cast our votes, but defer to the whole country to tell us who to vote for?”
Nothing, from what I can see. Certainly not anything in the Constitution.
Sure, someone would bring it to the courts, but having a case, let alone a “blatant” one? That’s REDSTATEWAD partisanship speaking. An argument he wouldn’t be making if the two recent candidates denied the Presidency despite winning the popular vote were Republicans.
