My proposal: Tiered Approval Voting
I've been thinking a lot about a voting system that maintains single-member constituencies as an alternative to FPTP, two-round systems, IRV, etc.
I therefore opted for a system that would allow the voter to express four choices, one for each candidate, without having to vote for everyone and without using a vote transfer system or scores. So, in my system, the voter has a preferential (P) vote (for only one candidate) and can label any other candidate with accepted (A), neutral (N) or rejected (R).
During the counting each ballot is worth one vote only for each candidate, therefore the total is based on the total count of the ballots, excluding completely blank and invalid ballots.
To win, you need to obtain an absolute majority:
Round 1: We count the preferences. If no one wins, we eliminate candidates with less than 1/6 of the vote.
Round 2: We add the accepted votes to the preferences. If no one wins, we eliminate candidates with less than 1/4 of these combined votes.
Round 3: We add the neutral votes. If no one wins, we eliminate candidates with less than 1/3 of these combined votes.
Round 4: If a winner has not yet been established, the candidate with the lowest number of rejected votes wins.
If no one reaches these thresholds, the top two face off.
What do you think? I would really like to have an opinion on this system.
