- People could directly lower the chances of a main candidate they didn't like without contributing to polarization.
- People could vote without voting for someone whose values and policies they disagree with.
- People could use voting as an avenue to express political negativity and dissatisfaction.
- There wouldn't be as much of an incentive for smear campaigning. If a main party focuses on making the other party look bad, it might only cause people to vote against either party. To get positive votes, a party may have to advertise its own positive features.
- The candidates who attract the least antagonization would have a better chance.
Obviously it wouldn't be a perfect system, and I don't really know how it would turn out, but to me it seems like an improvement. What do you think?
