The author of this paper is Kevin Kosar. Conservatives have been generally hostile to electoral reforms, usually positioning them as efforts by “the left” to bias election results in their favor.
Republicans have succeeded in banning Ranked Choice Voting (RCV) in five states: Florida, Tennessee, Idaho, Montana and South Dakota. Sarah Palin complained bitterly about RCV after her RCV election loss for US House from Alaska in 2022, and there is an effort in Alaska to repeal RCV, even though polls have shown that it is popular with Alaskans.
RCV is popular with Republican Party members in at least two states: Utah and Virginia. The Utah GOP has long used RCV for internal party elections, and the Virginia GOP nominated Glenn Youngkin using RCV at its 2021 Gubernatorial nominating convention. He went on to defeat Democrat Terry McAuliffe in the November 2021 General Election. The Republican Party of Virginia has thereafter sometimes used RCV in privately run primary elections (historically called “firehouse primaries” in Virginia).
