User:RobLa/MATT
"Maximum approval top-two" (or "MATT") is a voting system that was proposed by User:RobLa, based on discussions that happened on the election-methods mailing list in 2018.[1][2] MATT uses the following steps:
- The candidate who receives the highest approval rating (the "front-runner") qualifies for the general election
- Example: if there are 100 voters, and 40 approve of "A" and "B", 30 approve of only "B", and 30 approve of only "C", then "B" advances to the general election, since "B" is approved by 70% of voters.
- A second candidate (the "complementary candidate"), who maximizes the approval of the electorate, also qualifies (i.e. by having the highest approval among voters that did not approve of the front-runner). If two candidates both satisfy an equal part of the remaining electorate, the candidate with the highest overall approval rating advances.
- Example: if there are 100 voters, and 40 approve of both "A" and "B", 30 approve of only "B", and 30 approve of only "C", then
- "B" advances with 70% approval (per step 1)
- "C" advances (per this step). "B" satisfies 70% of the electorate, and "C" satisfies the other 30%. So, 100% of the voters will be satisfied with one of their choices in the general election.
- Example: if there are 100 voters, and 40 approve of both "A" and "B", 30 approve of only "B", and 30 approve of only "C", then
