Vote limité
Résumé
Limited voting (also known as partial block voting) is a voting system in which electors have fewer votes than there are positions available. The positions are awarded to the candidates who receive the most votes absolutely. In the special case in which the voter may vote for only one candidate and there are two or more posts, this system is called the single non-transferable vote or sometimes the strictly limited vote.
The town of Voterville elects three representatives to the local legislature. At the election, the ballot paper appears thus:
The voter has only two votes, which they have cast for Brian and Beryl Blue. They cannot cast a third although there are three seats being contested. Each vote counts as one towards the total for the candidate voted for.
Limited Voting frequently enables minority groupings to gain representation – unlike first past the post or bloc voting systems. But it is not guaranteed to do this, since the effectiveness of a sectional vote may be altered depending on the number of candidates fielded and the manner in which votes are cast for parties.
For example, in Voterville 54% of electors support the Blue Party while 46% support the Red Party. Assuming an even distribution of support across the town, the Blue Party would win all three seats with either bloc voting or first past the post, and the Red Party would win no representation.
With limited voting the Red Party would usually win one seat.
However, it is still possible for one party to win all three seats or for the least popular of two parties to win more seats than the other.
It is possible for the Blue Party, even if it is the most popular party, to win only one of the available seats if it attempts to win all three and overreaches itself. Since they have nearly 60% of the vote, they may be tempted to try to win all three seats. To do this, they need only to field three candidates. The Red Party, aware of their relative weakness, choose only to contest two and thus to concentrate their vote.
