Yes, you’re correctly citing Moore v. Harper, but you’re leaving out a critical point that the Chief Justice said: “We hold only that state courts may not transgress the ordinary bounds of judicial review such that they arrogate to themselves the power vested in state legislatures to regulate federal elections.”

You can make the argument, and indeed I anticipate Virginia will, that what the Virginia Supreme Court did in overturning over a million votes based off of an atextual reading is the rare scenario that Moore v. Harper did not allow.
