Any notary public, United States postmaster, assistant United States postmaster, United States postal supervisor, clerk in charge of a contract postal station, or other officer having authority to administer an oath or take an acknowledgment may be an attesting witness; provided, however, that in the case of an absent elector who is temporarily or permanently physically disabled, the attesting witness may be any person eighteen (18) years of age or older and such person is not required to have the authority to administer an oath. If a postmaster, assistant postmaster, postal supervisor, or clerk in charge of a contract postal station acts as an attesting witness, his or her signature in a box on the elector's certificate must be authenticated by the cancellation stamp of their respective post offices. If an officer having authority to administer an oath or take an acknowledgment acts as attesting witness, his or her signature in a box on the elector's certificate, together with his or her title and address, but no seal, shall be required. A portion of the elector's signature extending outside of the box shall not be grounds for rejecting that elector's ballot. Any affidavits made by an absent elector who is in the Armed Forces may be executed before a commissioned officer, warrant officer, or noncommissioned officer not lower in grade than sergeant rating or any person authorized to administer oaths.
