The bill amends Chapter 17-12.1 of the General Laws, focusing on the presidential preference primary elections. Key insertions include the implementation of ranked choice voting, allowing voters to rank up to five candidates and introducing an option for "uncommitted." The bill mandates that the party's state committee must certify the number of delegates and their allocation methods to the secretary of state by the first Tuesday in January before the primary. It also clarifies that if a party does not specify ballot tabulation methods, the election will default to a statewide winner-take-all approach. Additionally, the bill outlines the notification process for presidential candidates, including written notifications and petition requirements, and establishes clear procedures for candidate withdrawals.

Further amendments introduce new definitions and procedures for ballot tabulation, including the treatment of undervotes and the elimination of candidates during the counting process. The bill emphasizes the importance of post-election audits, mandating risk-limiting audits for primary, general, and special elections to ensure election integrity. It specifies that unofficial final results for presidential preference primaries will follow the guidelines of chapter 12.1 of title 17, and audit results must be published within 48 hours. The bill also includes new legal references regarding recount procedures while deleting outdated provisions, ultimately aiming to enhance transparency and accuracy in the electoral process for presidential primaries.
