(b) If a voter does any of the following, the voter's vote is void:
(1) The voter votes for more than one (1) candidate, and the candidates are not on the official primary ballot of the same political party.
(2) The voter votes for a candidate who is not on the official primary ballot of any political party.
(3) The voter votes for a candidate who is on the official primary ballot of a political party, but the voter does not indicate the office for which the candidate seeks to be nominated.
(c) If the voter votes for a political party, but the voter does not vote for any individual candidates who are on that political party's official primary ballot, the voter's vote is void.
