Voting is the process of choosing one or more officials or representatives by casting an oral vote or a ballot, a document that formally expresses voter's preference or preferences as to whom should be elected or whom the voter likes and thinks has best chance to be elected. Voting can also be used to decide on policy usually by a majority but sometimes a super-majority is required. In Republics and representative democracies, a portion of the population votes to choose representative government members.
Electoral systems, the procedure for converting votes cast into winners, vary depending on both the country and the political office. In many countries organizations work to reform the election system, usually to make it fairer and ensure that as many votes as possible are used to elect the winners.
