Binomial System

The binomial electoral system is a variant of proportional representation in small constituencies. In this case, per constituency elected two candidates ( Two People constituency) and not determined by the statewide ratio of votes. This electoral system is used in the parliamentary elections in Indonesia and Chile.

Method

According to the binomial electoral system ( also the name of bi- nomial therefore ) be two candidates in each constituency distributed on the basis of votes for the constituency lists of political parties and election links within this constituency.

Maintains the victorious list more than twice as many votes as the second strongest list, so their candidates are elected and get the two seats. Otherwise, depending on a candidate list with the most votes and the list with the second most votes are elected deputies in the constituency. The other parties and dial-up connections get nothing - the votes they have no influence on the distribution of seats in Parliament. In this respect, the binomial system is similar to the majority vote, in which, however, only one candidate per constituency is elected.

Within the lists of candidates are freely selectable. The votes for each candidate in the list are added to the overall result of the list. Win the list a seat, the list is selected candidate with the most votes, it will win both seats, the two list candidates are elected with the most votes. In the latter case, it may happen that a candidate an inferior list is not elected, though he has received more votes than the second candidate of the winning list.

The binomial method favors a two-party system of moderate groups according to the U.S. model, but prevents the parliamentary representation of small parties, provided they are received no alliance with larger parties.
