Electoral reform in the United States

Electoral reform in the United States refers to the efforts of change for American elections and the electoral system used in the US. United States House of Representatives elections are generally conducted in single-member (SMD) first-past-the-post elections (FPTP). Senate seats are elected statewide, generally in staggered terms in FPTP elections, although some states use ranked-choice voting, jungle primaries, or runoff elections.
