There are different methods for evaluating the spare votes: • One-step procedure: All votes for parties that are below the electoral threshold according to the first preferences are discarded; in their place, the spare votes for these voters are counted. This is
party list version of the
contingent vote (if the voters may rank all parties) or
supplementary vote (in case of just one spare vote). • Multi-round procedure: First the party with the lowest number of first preferences is eliminated, and the spare votes from its voters become effective. This is repeated until only parties that are above the electoral threshold are left. The benefit compared the one-step procedure is that some political parties could pass the electoral threshold only once spare votes become effective. This is the party list equivalent of the
single transferable vote, which the quota being the electoral threshold. Limiting the ranking of parties to two ranks allows a faster ballot counting procedure, where every electoral district reports only the counts of each party-pair. This procedure does not require all electoral districts to wait until the determination which parties have crossed the electoral threshold is finalized. With more than two ranks of parties, the voters rank several spare votes/parties according to their preferences. In this process, a voter's party vote is carried over until it either goes to a party that is above the electoral threshold or has passed through all of the voter's stated preferences. The spare vote can also be used in the proportional part of
mixed electoral systems with electoral thresholds, and some mixed systems operate on the basis of an indirect spare party vote (
mixed single vote) to reuse the candidates that did not receive a direct mandate in favour of the party list they are affiliated with. The second vote under
mixed-member proportional systems may be considered a direct Spare vote for a party, but not relating to the electoral threshold, but for the case when a voters favourite local candidate does not win in their district. This is also the case for the party list preference in the
mixed ballot transferable vote (MBTV), which is may also use a ranked ballot capable of functioning a contingent party vote if combined with an electoral threshold. It is also the mixed equivalent of the spare vote (and
STV, the non-partisan equivalent of the spare vote), meaning the spare vote is used in a two-tier election, and the spare vote is used on the upper (party-list) tier only if it would be wasted on the lower (candidate-based) tier. The process is the same as under the positive vote transfer mechanism of the mixed single vote (MSV), except under MSV, voters do not get to choose their party preference, it is defined by the candidate vote. The
modified d'Hondt electoral system is another preferential party system, which allows to rank parties. It is a variant of
single transferable voting, where an
electoral threshold for parties is applied. == Proposals ==
