Plurality block voting

The m candidates with the most votes (who may or may not obtain a majority of available votes or support from the majority of the voters) are declared elected and will fill the positions.

Due to multiple voting, when a party runs more than one candidate, it is impossible to know if the party had support of as many voters as the party tally of votes (up to number of voters participating in the election) or if it had support of just the number of voters equivalent to the votes received by the most popular candidate and the other candidates of that party merely received votes from subset of that group.

Candidates are running in a three-member district; each of the 10,000 voters may cast 3 votes (but do not have to). Voters may not cast a more than one vote for a single candidate.

Party A has about 35% support among the electorate, Party B around 25% and the remaining voters primarily support independent candidates.

Candidates of Party A won in a landslide, even though they only received a plurality (35–37%) among the voters (10,000). This is because most parties run as many candidates as there are open seats and voters of a party usually do not split their ticket, but vote for all candidates of that party.

By contrast, a single transferable vote system would likely elect 1 candidate from party A, 1 candidate from party B and 1 independent candidate in this scenario.

Under block voting, a slate of clones of the top-place candidate may win every available seat. A voter does have the option to vote for candidates of different political parties if they wish, but if the largest group of voters have strong party loyalty, there is nothing the other voters or parties can do to prevent a landslide.

While many criticize block voting's tendency to create landslide victories, some cite it as a strength. Since the winners of a block voting election generally represent the same slate or group of voters, there is greater agreement amongst those elected, potentially leading to a reduction in political gridlock.

Bullet voting is a strategy in which a voter only votes for a single candidate in an attempt to stop them being beaten by additional choices. Because the voter is essentially wasting a portion of their vote, bullet voting is only a good strategy when the voter has a strong preference for their favourite and is unsure of, and/or indifferent to, the other candidates' relative chances of winning, for example, if the voter supports an independent candidate or a minor party which has only nominated one candidate.

The following countries use plurality block voting (not including party block voting using plurality) in their national electoral systems:

Block voting was used in some constituencies for the House of Representatives of Japan in the first six general elections between 1890 and 1898: while the majority of seats was elected by plurality in 214 single-member districts, there were 43 two-member districts that elected their representatives by block voting.
