# Difference between revisions of "Endorse/Accept/Reject voting"

Voters “Endorse”, “Accept”, or “Reject” each candidate. The winner is the most-endorsed candidate who isn’t “overwhelmed”. A potential winner is “overwhelmed” if there are fewer voters who don’t reject the potential winner, than voters who don’t reject some other candidate while also rating them at least as high as the potential winner.

(Note: there will always be at least one candidate who is not overwhelmed, because you always count at least as many votes for a candidate when you’re considering them as a potential winner as when you’re seeing if they overwhelm another candidate.)

## Criteria compliances

This system is monotonic and meets the majority criterion and the mutual majority criterion. If there are no more than three candidates such that every ballot endorses at least one of the three and rejects at least one of the three, then it meets the majority Condorcet winner and majority Condorcet loser criteria.

## An example

Imagine that Tennessee is having an election on the location of its capital. The population of Tennessee is concentrated around its four major cities, which are spread throughout the state. For this example, suppose that the entire electorate lives in these four cities, and that everyone wants to live as near the capital as possible.

The candidates for the capital are:

• Memphis on Wikipedia, the state's largest city, with 42% of the voters, but located far from the other cities
• Nashville on Wikipedia, with 26% of the voters, near the center of Tennessee
• Knoxville on Wikipedia, with 17% of the voters
• Chattanooga on Wikipedia, with 15% of the voters

The preferences of the voters would be divided like this:

42% of voters
(close to Memphis)
26% of voters
(close to Nashville)
15% of voters
(close to Chattanooga)
17% of voters
(close to Knoxville)

Assume voters in each city endorse their own city; accept any city within 200 miles except the farthest; and reject any city that is over 200 miles away or is the farthest city. (These assumptions can be varied substantially without changing the result, but they seem reasonable to start with.)

City Endorse Accept Reject Score against Memphis Score against Nashville
Memphis 42 0 58 42 42
Nashville 26 74 0 58 100
Chattanooga 15 43 42 58 32
Knoxville 17 41 42 58 32

Memphis is overwhelmed by Nashville; Nashville is not overwhelmed, and so wins. This is a strong equilibrium: no subgroup could get a better result through strategy.
