It seems nobody cares about that sort of thing anymore. Voters vote “my guy” / “my tribe” and ignore the rest. And as long as the GOP can be blackmailed by the Trump faction, it won’t move a whole lot.
Approval voting is simpler to understand, simpler to implement, and leaves people more satisfied on the whole. I think it's a better and more achievable goal than ranked-choice systems as a replacement for our utterly broken FPTP system.
