Only citizens of the United States, including occupants of soldiers' and sailors' homes, over the age of eighteen who are residents of this state and of the political subdivision in which they offer to vote are entitled to vote at all elections by the people, if the election is one for which registration is required if they are registered within the time prescribed by law, or if the election is one for which registration is not required, if they have been residents of the political subdivision in which they offer to vote for thirty days next preceding the election for which they offer to vote: Provided however, no person who has a guardian of his or her estate or person by reason of mental incapacity, appointed by a court of competent jurisdiction and no person who is involuntarily confined in a mental institution pursuant to an adjudication of a court of competent jurisdiction shall be entitled to vote, and persons convicted of felony, or crime connected with the exercise of the right of suffrage may be excluded by law from voting.

Section 3.

1. All elections by the people shall be by paper ballot or by any mechanical method prescribed by law.
2. Voters shall have only a single vote for each issue on which such voter is eligible to vote. Voters shall have the same number of votes for an office as the number of open seats to be elected to such office at that election. Under no circumstance shall a voter be permitted to cast a ballot in a manner that results in the ranking of candidates for a particular office. Notwithstanding any provision of this subsection to the contrary, this subsection shall not apply to any nonpartisan municipal election held in a city that had an ordinance in effect as of November 5, 2024, that permits voters to cast more than a single vote for each issue or candidate on which such voter is eligible to vote.

All election officers shall be sworn or affirmed not to disclose how any voter voted; provided, that in cases of contested elections, grand jury investigations and in the trial of all civil or criminal cases in which the violation of any law relating to elections, including nominating elections, is under investigation or at issue, such officers may be required to testify and the ballots cast may be opened, examined, counted, and received as evidence.

2. The person receiving the greatest number of votes at the general election shall be declared the winner.
3. Notwithstanding any provision of this section to the contrary, this section shall not apply to any nonpartisan municipal election held in a city that had an ordinance in effect as of November 5, 2024, that requires a preliminary election at which more than one candidate advances to a subsequent election.
