On February 16, the Hawaii Senate Judiciary Committee passed SB 1005 by 4-1. It establishes a presidential primary. Hawaii is one of the few states that has never held a government-administered presidential primary.
All qualified parties would be eligible for a presidential primary. Presidential candidates would need 100 signatures plus a filing fee of $3,000, although if they sign a pledge to voluntarily limit their campaign spending, the fee would be $2,675. Indigent presidential candidates could avoid the fee if they submit a petition of one-half of 1% of the registered voters, which would be approximately 4,000 signatures. Thanks to Josh Putnam for this news.
The presidential primary would be in March.
Chances are that they would be competing with other primaries on the mainland, and only outsiders who needed a win somewhere would show up.
