Plurality electoral system

The plurality voting system is a single-winner voting system often used to elect executive officers or to elect members of a legislative assembly which is based on single-member constituencies.The most common system, used in Canada, India, the UK, and the USA, is first past the post or winner-takes-all, a voting system in which a single winner is chosen in a given constituency by having the most votes.In some countries such as France a similar system is used, but there are two rounds: the "two-round" or "two-ballot" plurality system. The two highest-voted candidates of the first round compete in a two-candidate second round or all candidates above a certain threshold in the first round compete in a two-, three- or four-candidate second round. If one candidate has a majority of votes in the first round, there is no second round.
