Any ranked voting method will tend to prefer two parties with varying levels of strength.
Ordinal voting systems, on the other hand, are immune to Arrow’s Theorem, or rather it doesn’t apply to them. I like STAR as an option. It seems to be the best single winner voting system available. There are also multi-winner versions that are better than any other multi-winner system currently in use, but that’s its own can of worms.
STAR is a cardinal voting system, not an ordinal system. And Gibbard showed that cardinal voting systems suffer from the same issues that Arrow demonstrated for ordinal systems.
No. Because of Arrow’s Impossibility Theorem.
