All federal and state elections are partisan races. That means in the primary, voters must live in the geographic district designated and can only vote in the primary of one party.
In Hawai'i, most voters pull Democratic primary ballots because that's where most of the action is. The top vote-getter in each party in each primary race goes on to face the other top voter-getter of the other parties in the general election.
In the primary, the governor and lieutenant governor run separately. In the general election, the winners in each party for those two offices are paired and run as a team.
All county races are non-partisan. That means candidates do not declare a party affiliation. Though some of the races require that the candidates live in a particular geographic region, all registered Maui County voters can vote in all Maui county races for mayor and for all nine members of the County Council. In these races, the top two vote-getters go on to face each other in the general election.
