The Democratic primary is sometimes more important than the general election.
Hawaii has open primaries, unlike most states. That means no one registers with the state as a member of a party, and any voter can choose anonymously to vote in any one primary. Newcomers should learn the historical reason for that.
Hawaii is now heavily Democratic. Before 1954, it was controlled by the Republican Party and the large landowners, and you could be (and often were) retaliated against if you voted as a Democrat. The Democratic revolution of 1954 changed all that. Now which primary I vote in is a secret between me and the ballot box.
I am a member of the Democratic Party. Nowadays, many practical people pretend to be Democrats and run for election in the Democratic primaries, even when they ought to be running in a Republican or Green or Libertarian or other primary. Some people whom even the Tea Party would reject as too racist, too homophobic, too anti-feminist, too nuts pretend to be Democrats.
The Hawaii Democratic Party platform is the consensus of what its members agree on. You can check it out if you Google "Hawaii Democratic Platform." Not all candidates running as Democrats support the platform. Some are flagrantly in opposition to it.
The moral is: You cannot depend on a party label to tell you what a candidate's policies are. You have to individually check on his/her views that matter to you.
