Ranked Choice Voting

Elections & Redistricting
Local Government

This memorandum provides an overview of ranked-choice voting, or instant-runoff voting.  Ranked‑choice voting (RCV) is currently used in some nonpartisan elections in three Colorado municipalities, with an additional two municipalities using it in future elections.  House Bill 21-1071, passed in the 2021 legislative session, may lead to more municipalities using RCV in nonpartisan elections beginning 2023.

The effective date for bills enacted without a safety clause is August 7, 2024, if the General Assembly adjourns sine die on May 8, 2024, unless otherwise specified. Details
