When submitting the certificate of ascertainment as required by 3 U.S.C. 6, the governor shall certify the state's electors to the archivist of the United States. The certificate must state that:
(1) the electors will serve as electors unless a vacancy occurs in the office of elector before the end of the meeting required under 13-25-307 (1), in which case a substitute elector will fill the vacancy as provided for in 13-25-306; and
(2) if a substitute elector is appointed to fill a vacancy, the governor will submit an amended certificate of ascertainment stating the names on the final list of the state's electors.
