In all likelihood they can declare an alternate slate, especially if the courts determine that the election was so fraudulent as to be invalid. But that is not the case here. The legislature did not appoint the GOP electors. The courts have not ruled the election to be invalid. This is a case where the electors are proclaiming themselves to be electors. Where does their validity come from?
‘This is a case where the electors are proclaiming themselves to be electors. Where does their validity come from?’
not really; the GOP legislators established this slate to protect against a future finding of an invalid election leaving the state without electors...
their validation comes from the constitution...
