All elections by the people shall be by direct and secret vote. General elections shall be determined by a plurality of votes cast. Registration and elections shall, and political party functions may, be regulated by law; however, the requirements for a candidate with no party affiliation or for a candidate of a minor party for placement of the candidate's name on the ballot shall be no greater than the requirements for a candidate of the party having the largest number of registered voters. Aside from Presidential candidates, all candidates running for a given office, regardless of their party preference, will appear on a single combined primary ballot, and individual voters can vote in secret for any candidate from any political party. If no candidate receives a minimum of fifty percent, only the two candidates who received the highest and the second-highest number of votes in the primary will appear on the ballot as candidates in the November General Election.
