Double simultaneous vote
Double simultaneous vote (DSV) is a feature of some electoral systems 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.
