I don't doubt any of this is true. But if anything, I think it just supports my point that under our current system, candidates do not pay attention to anything other than a select few cities. So the pro electoral college argument over candidates focusing on select few cities is a moot point.

All of them pretty much look to accomplish the same goal and can move us away from the 2 party, winner-take-all system.

They're all better than FPTP, but ranked choice voting in a way suffers from the same sort of issues as FPTP. The spoiler effect of FPTP is still present, not nearly as bad, but still present. Because at the end of the day, ranked choice voting is basically FPTP over several rounds. If FPTP is bad, then repeating it several times isn't good.

The other thing is that ranked choice isn't as secure as STAR or approval, which are purely additive, whereas ranked choice is not. Pure addition makes it much easier to audit results, which is incredibly important. Additive results also allow us to see the results being collected in real time so to speak, which goes a long way towards trust in the system. Ranked choice just doesn't have that ability.

The other problem with ranked choice is that it doesn't really give somebody a quantitative say in how much they like/dislike candidates. I might prefer a candidate order of B, C, then E. But if I absolutely revile E, don't care either way about C, and am in love with B, the vote won't really show that. Approval has this problem as well, but it is a minor gripe to be honest.

Either way, all 3 of these will help deal with the 2 party situation. But if we have a choice, STAR is the best in my opinion.
