Voter turnout in 2020 elections caused a change in the number of valid signatures required for initiatives and veto referendums in 10 of the 26 states with at least one form of statewide initiative or referendum.
Signature requirements are determined differently depending on the state and, in 2022, will vary from 16,961 for initiated statutes in South Dakota to 997,139 for initiated amendments in California.
The majority of states with citizen-initiated measures—16—base signature requirements on ballots cast for gubernatorial candidates in the preceding gubernatorial election. Four states base signature requirements on total ballots cast in the preceding general election. Of the remaining states, three states base requirements on registered or active voters, one state bases requirements on voters for presidential candidates within the state, one state bases requirements on votes cast for secretary of state candidates, and one state bases requirements on the state population.
Below are some of the changes to ballot measure signature requirements caused by 2020 voter turnout:
• Ballot measure signature requirements increased by a range of between 7.4% and 44.2% in ten states.
• Signature requirements in the four states that base requirements on either presidential election turnout or gubernatorial election turnout in presidential election years increased by between 7.4% and 25%.
• Signature requirements for the four states that base requirements on general election turnout increased by between 26.8% and 44.2%.
• In those four states, turnout was higher than in 2016 as well, causing between 7.6% and 25.1% higher signature requirements than following the last presidential election.
• Signature requirements in the two states that base requirements on voter registration increased by 18% and 18.6%, respectively.
• Washington’s initiative signature requirement increased by 25% to 324,516 for 2021 through 2024. Since at least 2008 when the requirement was 224,880, Washington’s requirement has increased every four years by between 2% and 7%.
