The Hawaii state elections office website lists the parties that have asked for petition blanks, so as to try to qualify as a party. The requirement is 861 signatures (one-tenth of 1% of the number of registered voters).
Parties already on are Democratic, Republican, Libertarian, and No Labels. The Solidarity Party has submitted a petition, which is being checked.
Here is the list: Aloha Aina, American Shopping, Free Will, Green, New Republican, Socialism & Liberation, Royal Hawaiian Kingdom, We the People, WXYZ Next Day, and the 1787 Party.
If the Party for Socialism & Liberation qualifies, it will be the first party with “Socialist” or “Socialism” in its name on the Hawaii ballot since 1912, when the Socialist Party was on and had a nominee for Delegate to the U.S. House.
