This explainer presents both sides based on the measure's text. It does not recommend a vote.
Plain English Summary
This measure changes how Colorado conducts elections by creating open primaries where all candidates appear on one ballot regardless of party, and implementing ranked choice voting where voters rank candidates in order of preference. If no candidate gets over 50% of first-choice votes, the candidate with the fewest votes is eliminated and their votes go to voters' second choices, continuing until someone has a majority.

Arguments For and Against
Arguments For
Supporters argue ranked choice voting with all-candidate primaries would reduce negative campaigning and elect candidates who appeal to a broader range of voters.— Kent Thiry, Prop 131 sponsor
Proponents contend the system prevents spoiler effects where similar candidates split votes and an unpopular candidate wins.
Arguments Against
Opponents argue ranked choice voting is confusing to voters, as demonstrated by implementation problems in other jurisdictions.— Colorado Republican Party
Critics contend the system benefits well-funded candidates who can run broader campaigns and disadvantages grassroots challengers.
