How Ranked Choice Voting Actually Works

Short version: Ranked choice voting lets you rank candidates in order of preference instead of picking just one. If nobody wins a majority of first choices, the last-place candidate is eliminated and their voters' ballots transfer to those voters' next choice. The counting repeats, round by round, until someone has a majority. It is designed to elect the candidate the most voters can live with, not just the one with the biggest angry plurality.

The one-sentence definition

Ranked choice voting (RCV), also called instant-runoff voting, is a system where voters rank candidates 1st, 2nd, 3rd, and so on, and the winner is decided through rounds of counting that eliminate the lowest candidate and transfer their votes until one candidate has a majority.

How the count works, round by round

  1. Count everyone's first choices. If a candidate has more than 50%, they win. Done.
  2. If nobody has a majority, eliminate the candidate in last place.
  3. Transfer that candidate's ballots to whoever each of those voters ranked next.
  4. Recount. Check again for a majority.
  5. Repeat until one candidate crosses 50%.

A ballot only ever counts for one candidate at a time, your highest-ranked choice who is still in the race. Your second choice never hurts your first choice; it only matters if your first choice is already out.

A quick example

Four candidates, 100 voters. First-choice totals:

  • Candidate A: 40
  • Candidate B: 31
  • Candidate C: 20
  • Candidate D: 9

Nobody has a majority, so D is eliminated. D's 9 voters ranked someone else second, say 6 go to C and 3 to B. New totals: A 40, C 26, B 34. Still no majority, so C is eliminated and those ballots transfer to their next choice. If most prefer B, B crosses 50 and wins, even though A led the first round. That last part is the thing people argue about, and it is the whole strategic point.

Why it changes how campaigns are run

Under a normal "pick one" election, you win by turning out your base and tearing down the front-runner. Under RCV, you also have to be a lot of voters' second choice, because those transfers decide close races. That does three things campaigns notice immediately:

Where people get confused

Does my second choice hurt my first? No. Your ballot stays with your first choice for as long as they are in the race. Ranking a backup can never move a vote away from your top pick.

Is this the same as the top-four or top-five primary? Related but not identical. Several states pair an all-candidate primary (top four or five advance) with an RCV general. The RCV part is the ranked count above; the "top-four" part is just how the finalists are chosen.

Do I have to rank everyone? No. You can rank one, some, or all. If everyone you ranked is eliminated, your ballot is "exhausted" and stops counting, which is one of the real critiques of RCV.

Where RCV stands right now

RCV is at a genuine inflection point. Two states, Maine and Alaska, use it statewide, dozens of cities use it for local elections, and it is on ballots again this cycle. That includes a high-profile repeal fight in Alaska, where a 2024 attempt to repeal it failed by about a quarter of a percentage point, alongside adoption measures in cities like Honolulu and Irvine. Whichever way those votes go, the debate over whether ranking candidates makes elections better is not settling any time soon.

Reading about the center squeeze is one thing. Watching your comfortable first-round lead evaporate in the transfers, because you were nobody's second choice, is another.

Frequently asked questions

What is ranked choice voting in simple terms?
It is a voting system where you rank candidates in order of preference. If no candidate wins a majority of first choices, the last-place candidate is eliminated and their votes transfer to voters' next choices, repeating until someone has a majority.
Does ranking a second choice hurt my first choice?
No. Your vote counts for your first choice as long as that candidate is still in the race. Your second choice only comes into play if your first choice has been eliminated.
What is the difference between ranked choice voting and instant-runoff voting?
They are the same thing for a single-winner race. "Instant-runoff voting" describes the round-by-round elimination method; "ranked choice voting" is the common name for the ballot where you rank candidates.
What is the "center squeeze" in ranked choice voting?
It is when a broadly-liked moderate candidate gets few first-place votes, is eliminated in an early round, and never reaches the final count, even though they might have beaten either finalist one-on-one.
Do I have to rank every candidate?
No. You can rank as many or as few as you like. If all the candidates you ranked are eliminated, your ballot stops counting.
Where can I try ranked choice voting myself?
The Ranked Choice, a free browser game at Campaign Margins, lets you run a full ranked-choice campaign and see the round-by-round count play out.
