Score voting avoids the vagaries and gaming that are intrinsic to preference ranking systems. It is simpler and more reliably reflects the will of voters. You have probably used it if you have completed a survey. We should use it in political elections.
The 2018 Victorian election has turned up another result in which ‘preference whispering’ by minor parties has distorted the will of the people ($, William Bowe at Crikey), if we take the will of the people to be indicated by first-preference votes.
Minor parties scored 25% of upper house seats from 20% of first-preference votes, whereas the Greens scored only one seat with votes that exceeded almost all minor-party votes individually. In one case a primary vote of 1.3% beat a Greens primary vote of 13.5%.
