Email Chain on Ranked Choice Voting and Electoral Politics (File 026508)
Email correspondence between Larry Summers, Eric Maskin, and Jeffrey E. discussing ranked choice voting (RCV) systems, their impact on electoral outcomes, turnout, and political polarization, with references to the 2016 presidential election.
Summary
A detailed email exchange from September 2018 examining ranked choice voting as an alternative electoral system. Eric Maskin, a voting theory expert, explains how RCV could promote centrist candidates over extremists and references the 2016 election, discussing how RCV might have allowed Bernie Sanders to run as an independent without helping Trump win, potentially changing outcomes in Michigan, Wisconsin, and Pennsylvania. Larry Summers raises concerns about RCV's complexity potentially depressing African American and lower-income turnout, and questions whether it would clearly promote centrism. The conversation includes discussion of game theory, voter behavior, and the potential unintended consequences of electoral reform.

But also more centrists (e.g., Bloomberg). Since thecentrists are closer to the median voter, they will defeat the extremists.The evidence I have seen suggests that RCV increases turn-out. [But it's important that voters be given thechoice to rank as many or few candidates as they like, so that a voter always has the option of voting for asingle candidate (in effect, he would be ranking all other candidates as tied for second). In practice, most voterschoose to rank two or three candidates, but a significant fraction just rank one]In fact the increase in the diversity of candidates under RCV is related to turn-out. If RCV had been used in2016, Bernie Sanders could have run as an independent in the general election without fear of guaranteeing aTrump victory. Many of the Bernie supporters who stayed home on election day might then have voted---andpresumably would have ranked Clinton second. This would have given lier a victory over Trump in Michigan,Wisconsin, and Pennsylvania (and possibly elsewhere).EricFrom: LHS <Sent: Tuesday, September 11, 2018 7:52 PMTo: Maskin, EricCc: lhsofficeSubject: Re: This morningI get that formal argumentWhat about aspects not quite in model.More folk will run from extremes if they can attract more First run votes. Candidates can position a bit.Separately I pitched this to someone today.He said he had heard that because of its greater complexity African American and lower income turnout wasdepressed.

I'm glad you found it worthwhile, and I agree withyou that Adam Friedman's commitment to the project is impressive.I AM serious about working on this---it's a nice opportunity to make important practical use of someinteresting theory. Voting rules may seem nerdy and dry, but they can make an enormous difference to actualpoliticsThe formal argument that RCV promotes centrism better than the current system (plurality rule) isstraightforward. Suppose that most voters vote ideologically in the sense that the closer a candidate is to theirown position on the left-right spectrum, the more like they are to vote for him. Then under majority rule (myfavorite voting system)---in which voters rank candidates and the winner is the candidate who beats all other inpairwise comparisons----the winner will be the median voter's favorite candidate-----in other words, the mostcentrist candidate gets elected (this assumes that there are enough candidates running so that there is one whois 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, EricFrom: LHS .MI 'Sent: Tuesday, September 11, 2018 4:16 PMTo: Maskin, EricCc: lhsofficeSubject: This morning IIt was fun and interesting.I admire your friends determination.Are you serious about working on this?Has anyone done a full analysis of this and polarization.Seems like on one hand it might encourage Ralph Nader cuz he d get more first round votes and not electGeorge bush. This might be bad.HOUSE OVERSIGHT 026510On other hand, gore would not have to move left to take Nader vote.If I like centrism is it clear that this is better.I get that it avoids arbitrary outcomes but assume that a tea party nut is as likely to elect a dem as a lefty is toelect et a republican.Anyway thanks for setting up.Btw I gave them 10,000.LarrySent from my iPadPlease direct all scheduling inquiries to my office at:Follow me on twitter glhsummerswww.larrysummers.complease noteThe information contained in this communication isconfidential, may be attorney-client privileged, mayconstitute inside information, and is intended only forthe use of the addressee.
