Illinois law dean and professor Vikram David Amar discusses a legal challenge to Maine’s Ranked-Choice Voting system, filed by a Republican incumbent and three Republican Maine voters following the November 2018 mid-term election. Amar breaks down the crux of the lawsuit while also unpacking the logistics of a rank order voting system like Maine’s. Providing examples of how rank order voting could work in presidential elections, Amar uses illustrations of past election results to highlight how their outcome might have differed under such a voting system while addressing such a system's limitations.
