The significant problems we have cannot be solved at the same level of thinking with which we created them.

Voting System Goals
We start with a few fundamental goals:

Build consensus

Share

Treat everyone equally

Play nice
In practical terms, this means:

Each interest group has their fair share of power

Elected representatives are approved by the greatest possible number of voters

Governing bodies reflect the diverse interests of those represented

The greatest possible number of citizens have at least one sympathetic ear among their representatives

Discussions among representatives reflect discussions among those represented

In local elections, all voters to have a say about every city or county representative (no districts). By extension, all representatives are accountable to all voters.

Voting without fear of unintended consequences or strategic voting dilemmas such as:

Fear of "wasting" a vote on a preferred candidate that many say can not win.

Inadvertently contributing to the election of the candidate a voter likes least by voting for a "longshot" or otherparty candidate.

Diluting the voting power of a party or interest group due to votesplitting among several similar candidates.
Secondary concerns are:

Reducing the cost of winning

Discouraging negative campaigning

Reducing the influence of gerrymandering
If you’re not satisfied with the results of past elections at all levels (local through national), remember the adage,
"If you do what you’ve always done, you’ll get what you always got."
Changes at the state and federal levels often begin with local reforms.
In many of our life decisions, we don’t just choose one option, and then let others choose for us if our top selection isn’t available.
We prioritize items on our todo lists. We make backup or contingency plans if our first effort doesn’t work out.
If our first choice isn’t available, we expect the opportunity to make another selection from all the remaining options.
If the ice cream store is out of our favorite flavor, we want to select an alternate from all the store’s flavors,
not just the two flavors chosen most often by other customers. Why should we settle for less when we choose those who influence many aspects of our lives?
RankedChoice Voting

The simplicity of a single election to determine the winner

A familiar process regardless of the number of candidates

The power to express your preference for every candidate
Rankedchoice voting (RCV), also known as InstantRunoff Voting (IRV) or SingleTransferable Vote (STV), fulfills the above goals.
In an RCV election, voters rank candidates in order of preference, much like prioritizing items on a todo list.
Voters who want to keep it simple can mark just one candidate and leave the other selections blank.
Those who have nuanced opinions can express their preference for every candidate.
Primary elections ask voters "who is your most preferred candidate?".
General or runoff elections ask, "Who is your mostpreferred (or leasthated) candidate of those remaining?".
RCV elections ask both questions on the same ballot.
RCV uses the familiar process of a runoff between a reduced number of candidates but gets results
with one election because voters are asked for their 2nd (and 3rd, 4th, etc.) choices on one ballot.
Imagine multiple runoff elections with one less name on each runoff ballot but you only need to cast one ballot.
The votecounting computer has the information it needs to tabulate as many runoffs as required until one candidate gets over half of the votes.
See the example below.
RCV has the obvious result of eliminating the need (and cost) of a separate runoff election if there’s no majority winner in the first round.
RCV builds consensus as voters who have their firstchoice
candidate eliminated in one round can choose a likeminded candidate in the next runoff round. A voting block with three candidates running
will reach consensus on one of the three through multiple runoff rounds of vote counts.
This eliminates problems due to multiple, similar candidates splitting the vote and unintentionally contributing to a win by a very different candidate.
"Longshot" candidates will not affect the final outcome. If they really have few supporters, they will be eliminated in an early round and
those who voted for them can cast their secondchoice vote for a "mainstream" candidate. If the candidate has many sympathizers, it could lead to a surprise
upset as voters can vote for anyone as their first choice without fear of unintended consequences.
RCV helps weed out extreme candidates as voters from a minority party or interest group can influence which candidate from a majority party or interest group wins.
RCV discourages negative campaigning. Suppose you’re ranking candidates A, B, and C.
The race is close, and the winner will need some secondchoice votes to reach the 50% threshold.
You fully support candidate B as your first choice, but are uncertain how to rank A or C.
Then candidate A says, "Candidate B eats puppies. Don’t vote for that puppy killer". Will that influence who gets your secondchoice vote?
RCV also works for multiwinner elections such as city councils, school boards, and county supervisors,
and achieves the goal of giving each interest group a fair share of power.
See the example below.
The links page has more on RCV and where it is used now.
RCV SingleWinner Example
Choose 1 winner from 3 candidates
Simplified example with 30 voters, 16 votes needed to win (50% + 1).
Round 1
The gray candidate got 12 votes which is more than either the orange (10 votes) or blue (8 votes) candidates.
We could say gray is more popular than orange or blue. We could also say "not gray" is more popular than gray
since 18 voters (60%) want someone other than the gray candidate.
One of the goals is to build consensus
Nobody got a majority, so we continue to round 2.
The blue candidate got the fewest votes and is eliminated.
The computer now counts everyone’s votes again, this time using the secondchoice votes of everyone who selected blue as their first choice.
6 of them selected orange as their second choice, 2 selected gray.
Round 2
Eliminated
If there are more than three candidates, the process would repeat as needed.
One candidate is eliminated at the end of each runoff round, and all votes are counted again in each following runoff round until one candidate gets
over half the votes.
RCV for Fair Representation
Majority Control with Minority Representation
If you’re not at the table, you’re on the menu
A multiwinner RCV election uses the same principles but has an additional goal of fairly allocating power among
the various interest groups.
The first step is to decide who gets a seat at the table, and how many seats each interest group should get. If the
largest interest group includes 3/5ths of the voters, and 2 smaller interest groups each include 1/5th of the voters, we
would expect the largest group to get 3 of 5 council seats for majority control,
and the other 2 groups to each get one seat for minority representation. Power is fairly allocated among the various groups.
It’s important
to understand that the groups are fluid and divisions may change from one election to the next. One election, the
groups might be based on ethnicity. The next election the divisions may be philosophical differences about
a community issue that spans ethnic lines.
If there are more interest groups than seats, only the larger groups get a seat, but everyone has a say about all
the candidates. Smaller groups might build consensus by ranking candidates in a similar way, and together select
one winning candidate.
We want to set the minimum votes needed to win a seat appropriately to provide a fair share of power to everyone.
If we make the winning threshold too small, there could be 4 winners for 3 seats.
If we make it too big, it’s harder for minority groups to get a seat
at the table and a bare majority (51%) is less likely to elect a majority of the representatives.
The votecounting computer precisely calculates the optimal winning threshold as 1/(n+1) + 1 where n is the number of winners.
If electing 3 council members, any candidate getting (1/4 + 1) of the total votes is elected. A group with twice
that many votes (1/2 + 2) could elect 2 candidates. A large interest group with 3 times the threshold (3/4+3),
could fill all three seats.
What happens if a candidate gets more than the minimum votes needed? Suppose there are 3 likeminded candidates
from a large interest group including 60% of the voters. Previously, we said that a large interest group including
60% of the voters should get 3 of 5 seats. What if the firstchoice votes were very lopsided with 1 of the 3
candidates getting 50% of the firstchoice votes, and the other two getting only 5%? If we eliminate the candidate
with the fewest votes, we might eliminate a candidate from the large group we expect to produce 3 winners.
Furthermore, the 50% voting for the same candidate would likely prefer either of the other 2 similar candidates
over any others.
RCV solves this problem with some 5thgrade math such as fractions, percentages, and decimal places.
If you’re not interested in the details, skip ahead to the example.
We go back to the winning threshold. Any votes over this amount are a surplus.
The winning candidate keeps just enough votes to win and the surplus votes are allocated to other
candidates based on the secondchoice preferences of everyone who voted for the winning candidate.
Each voter has one vote, but that vote can be split among multiple winners based on calculations by the computer to
achieve our goals of fair representation and treating everyone equally.
Hand counting is possible using simpler, less precise methods.
Multiwinner RCV builds consensus, allocates power fairly, and gives everyone a say about all the winners. It also makes
gerrymandering irrelevant as power is automatically distributed among interest groups, not accrording to district boundaries.
Multiwinner RCV could be used to elect United States congress members by switching from
singlemember congressional districts to multimember districts.
RCV MultiWinner Example
Choose 3 winners from 5 candidates
The Orange Clique vs. the Blue Clique
50 voters total: 30 blue, 20 orange
13 votes are needed to win (1/4 of 50 + 1).
The predicted result is two blue winners and one orange winner to give
fair representation to everyone and maintain majority control for the blue clique (30 of 50 votes or 60%), with
minority representation for the orange clique (20 of 50 votes or 40%).
Round 1
The blue/orange candidate got 16 votes which is enough to be elected, with 3 votes to spare. If we stopped here, the
winners would be the blue/orange, orange/red, and orange/brown candidates which violates the goal of fair
representation as the minority orange clique would have 2 representatives and the majority blue clique only one.
We’ll keep going to find the next 2 winners. The 3 surplus blue/orange votes now transfer to another candidate
based on each voter’s second choice. 10 of the 16 blue/orange voters selected the blue/purple candidate as their
second choice. The other 6 blue/orange voters selected the blue/gray candidate as their second choice.
The computer can calculate this vote split precisely as (62.5% of 3) votes for the blue/purple candidate,
and (37.5% of 3) votes for the blue/gray candidate.
We’ll approximate that in the example below as 2 more votes for the blue/purple candidate
and 1 more vote for the blue/gray candidate.
Note that the total number of votes stays the same, and each voter has exactly 1 vote.
Round 2
Still no second winner as no other candidate got more than the required 13 votes. The computer follows the next RCV
rule and eliminates the candidate with the fewest votes. In this example, the blue/gray candidate is eliminated, and
the computer looks at the secondchoice votes of all the blue/gray voters. All the blue/gray voters selected the
blue/purple candidate as their next choice which makes blue/purple the next winner.
Round 3
Eliminated
Now we’re down to just orange candidates. The computer continues following the RCV rules to find the third winner,
one of the orange candidates.
