In 3-2-1 voting, voters may rate each candidate “Good”, “Acceptable”, or “Rejected”. It has three steps:
- Find 3 Semifinalists: the candidates with the most “good” ratings. (If this is a partisan election, no two semifinalists may come from the same party).
- Find 2 Finalists: the semifinalists with the fewest rejections.
- Find 1 winner: the finalist who is rated above the other on more ballots.
Imagine an election for a high school mascot, in which the options are “Bulldogs”, “Lions”, “Tigers”, or “Knights”, with the following votes:
|Faction size||"Good" candidates||"Acceptable" candidates||"Bad" candidates|
|39||Bulldogs, Knights||Lions, Tigers|
|1||Bulldogs||Knights, Lions, Tigers|
The votes above lead to the following outcome:
|Candidate||"Good" ratings||"Acceptable" ratings||"Bad" ratings||2-way score|
The semifinalists are Tigers, Knights, and Bulldogs. The finalists are Tigers and Bulldogs. The winner is Tigers.
