In fact the increase in the diversity of candidates under RCV is related to turn-out. If RCV had been used in 2016, Bernie Sanders could have run as an independent in the general election without fear of guaranteeing a Trump victory. Many of the Bernie supporters who stayed home on election day might then have voted---and presumably would have ranked Clinton second. This would have given her a victory over Trump in Michigan, Wisconsin, and Pennsylvania (and possibly elsewhere).

More folk will run from extremes if they can attract more First run votes. Candidates can position a bit. Separately | pitched this to someone today. He said he had heard that because of its greater complexity African American and lower income turnout was depressed. Is there evidence on turnout impacts?

I’m glad you found it worthwhile, and | agree with you that Adam Friedman’s commitment to the project is impressive. | AM serious about working on this---it’s a nice opportunity to make important practical use of some interesting theory. Voting rules may seem nerdy and dry, but they can make an enormous difference to actual politics The formal argument that RCV promotes centrism better than the current system (plurality rule) is straightforward. Suppose that most voters vote ideologically in the sense that the closer a candidate is to their own position on the left- right spectrum, the more like they are to vote for him. Then under majority rule (my favorite voting system)---in which voters rank candidates and the winner is the candidate who beats all other in pairwise comparisons----the winner will be the median voter’s favorite candidate ----- in other words, the most centrist candidate gets elected (this assumes that there are enough candidates running so that there is one who is reasonably close to the median voter). Now observe that RCV is in between majority rule and plurality rule, and so will promote centrism better than plurality rule. Best wishes, Eric HOUSE_OVERSIGHT_026322
