Double simultaneous vote
Double simultaneous vote (DSV) is an electoral system in which multiple offices – such as the president and members of a legislature – are elected through a single vote cast for a party. It can be combined with other electoral systems; in Uruguay DSV is used to elect the president and members of the Senate and Chamber of Representatives, with the presidential election also using the two-round system; if no party/presidential candidate receives a majority of the vote, a second round is held for the presidential election.
Leveling seat
Leveling seats (tillægsmandat, utjämningsmandat, utjevningsmandater, jöfnunarsæti, Ausgleichsmandat), commonly known also as adjustment seats, are an election mechanism employed for many years by all Nordic countries (except Finland) in elections for their national legislatures. In 2013, Germany also introduced national leveling seats for their national parliament, the Bundestag. The electoral reform in Germany 2023 removed the leveling seats, and replaced with Zweitstimmendeckung.
Electoral list
An electoral list is a grouping of candidates for election, usually found in proportional or mixed electoral systems, but also in some plurality electoral systems. An electoral list can be registered by a political party (a party list) or can constitute a group of independent candidates. Lists can be open, in which case electors have some influence over the ranking of the winning candidates, or closed, in which case the order of candidates is fixed at the registration of the list.
