The Wyoming Democratic Party use ranked choice voting (RCV) in the 2020 presidential primary. See below for results and analysis.
How RCV works in presidential primaries
In elections with a 15% threshold to earn delegates (like in Wyoming), RCV eliminates candidates below the 15% threshold and transfers those ballots to those voters’ next choice candidate. This process continues until all remaining candidates are across the threshold. Delegates are awarded proportionally among the active candidates.
