In October 2017, Rhode Island Governor Gina Raimondo signed into law a groundbreaking election security measure. Now, state law requires Rhode Island election officials to conduct risk-limiting audits, the “gold standard” of post-election audits, beginning with the 2020 primary. A risk-limiting audit (“RLA”) is an innovative, efficient tool to test the accuracy of election outcomes. Instead of auditing a predetermined number of ballots, officials conducting an RLA audit enough ballots to find strong statistical evidence that outcomes are correct. The law, enacted in the aftermath of two critical events relating to the 2016 elections, stems from decades of advocacy aimed at increasing the efficiency, transparency, and verifiability of political contests in the state. Rhode Island is now the second state, joining trailblazing Colorado, to mandate use of this modern tool statewide.
Following the law’s enactment, a group of professionals with expertise in election security and election administration formed the Rhode Island Risk-Limiting Audit (“RIRLA”) Working Group. As its name suggests, the RIRLA Working Group was established to assess the conditions in Rhode Island to help the state as it prepares to implement the law. The RIRLA Working Group recommended – and Rhode Island officials agreed – that the state should conduct pilot RLAs in advance of the 2020 deadline. The Rhode Island Board of Elections chose January 2019 as the date for the pilots and, based on several factors, selected Bristol, Cranston, and Portsmouth, Rhode Island as participating municipalities.
Leading up to the pilots, the RIRLA Working Group had regular conference calls, meetings, and other correspondence to gain greater familiarity with Rhode Island’s election laws, practices, and voting equipment. In partnership with the state, the RIRLA Working Group set a goal to plan and develop a trio of pilot audits that would both meet the state’s needs and adhere to the Principles and Best Practices for Post-Election Tabulation Audits. Ultimately, the RIRLA Working Group drafted three separate audit protocols, step-by-step instructions to guide those who would conduct the RLAs over the course of two days.
