(a) Any ballot marked so as to identify the voter shall be void and not counted, except a ballot cast by a challenged elector whose name appears on the electors list; such challenged vote shall be counted as prima facie valid but may be voided in the event of an election contest. Any ballot marked by anything but pen or pencil shall be void and not counted. Any erasure, mutilation, or defect in the vote for any candidate shall render void the vote for such candidate but shall not invalidate the votes cast on the remainder of the ballot, if otherwise properly marked. If an elector shall mark his or her ballot for more persons for any nomination or office than there are candidates to be voted for such nomination or office, or if, for any reason, it may be impossible to determine his or her choice for any nomination or office, his or her ballot shall not be counted for such nomination or office; but the ballot shall be counted for all nominations or offices for which it is properly marked. Ballots not marked or improperly or defectively marked so that the whole ballot is void, shall be set aside and shall be preserved with the other ballots. In primaries, votes cast for candidates who have died, withdrawn, or been disqualified shall be void and shall not be counted. In elections, votes for candidates who have died or been disqualified shall be void and shall not be counted.

(b) At elections, any ballot marked by any other mark than a cross (X) or check ([checkmark]) mark in the spaces provided for that purpose shall be void and not counted; provided, however, that no vote recorded thereon shall be declared void because a cross (X) or check ([checkmark]) mark thereon is irregular in form. A cross (X) or check ([checkmark]) mark in the square opposite the names of the nominees of a political party or body for the offices of President and Vice President shall be counted as a vote for every candidate of that party or body for the offices of presidential electors. Any ballot indicating a write-in for any person whose name is not printed on the ballot and who properly gave notice of intent to run as a write-in candidate pursuant to Code Section 21-2-133 shall be counted as a vote for such person, if written in the proper space or spaces provided for that purpose, whether or not a cross (X) or check ([checkmark]) mark is placed before the name of such person.

(c) Notwithstanding any other provisions of this chapter to the contrary and in accordance with the rules and regulations of the State Election Board promulgated pursuant to paragraph (7) of Code Section 21-2-31, if the elector has marked his or her ballot in such a manner that he or she has indicated clearly and without question the candidate for whom he or she desires to cast his or her vote, his or her ballot shall be counted and such candidate shall receive his or her vote, notwithstanding the fact that the elector in indicating his or her choice may have marked his or her ballot in a manner other than as prescribed by this chapter.
