State legislatures have always had the authority and power to name electors autonomously. However, if they opt for elections via statute, the Feds have enormous influence on the process.
And there’s no way a legislature can overturn a “legal” vote and appoint electors contrary to the outcome of that vote.
No way.
Man, you are always on the wrong side of an argument.
The individual state legislatures can determine what is and what is not legal for determining the electors for President. If they determine that the vote was conducted fraudulently they can discard the popular vote and send their own slate of electors. Florida was prepared to do just that in 2000.
