ELECTIONS – Amends and adds to existing law to provide for a presidential primary election.

Idaho's H 638 establishes the state's first presidential primary election, replacing the previous caucus system. The bill sets the presidential primary date as the first Tuesday in March during presidential election years (amending Section 34-106) and creates new rules for candidate eligibility, ballot preparation, voting procedures, and delegate selection (through new sections 34-731 to 34-738). It also adjusts deadlines for voters to change party affiliation before the primary (amending Section 34-411A). This directly affects Idaho voters who will now select presidential candidates in a primary election rather than at caucuses.
