Primary Rules

How Hawaii's Primary Works

Hawaii uses different primary rules for state/congressional and presidential elections

State / Congressional

⚖
Open Primary
Any registered voter can vote in any party's primary, regardless of their own party affiliation or registration status.
How It Works
On election day, voters choose which party's ballot they want. They don't need to be registered with that party. In most open primary states, this choice is made privately at the polling place.
IVP's Position
Better than closed primaries, but still forces voters to pick a party's ballot rather than voting for the best candidate regardless of party.

Presidential

⚖
Closed Primary
Only voters registered with a political party can vote in that party's primary election. Independent and unaffiliated voters are excluded.
How It Works
Voters must register with a party, often weeks or months before the election, to participate. If you're registered as independent or unaffiliated, you cannot vote in either major party's primary.
IVP's Position
Closed primaries lock millions of independent voters out of the elections that matter most. In many districts, the primary is the only competitive election.
