I love approval voting the most by pure simplicity and effectiveness. How does score voting work better than STAR? I thought STAR degenerates into score voting when clone candidates run?

I haven't heard much of an argument against proportional voting before. Your article just casts doubt, but doesn't really make a decisive argument against. I actually don't like proportional voting because it reifies parties into the system, but I only support it because I think it can break the party duopoly and step towards better systems. I should rethink that.
