An example of a preselection procedure that gains extensive media coverage is the selection of candidates for President of the United States, referred to by one observer as 'the wildest democratic political bazaar in the world'.
[6] In Australia, the term has been in common usage since the 1920s to describe the selection of candidates by political parties for public office.
[7] These involved a two step process of a preselection ballot or plebiscite of party members and affiliated trade unionists in the electorate being contested, and endorsement, which was normally a formality, by the state executive.
Alternatively, there may be a more restricted group of selectors or selection may, in rare cases, be undertaken by an individual, such as a party leader.
[13] Some preselections are governed by additional rules that may serve to ensure a particular composition amongst candidates as a whole, or to facilitate other party objectives such as decentralisation of decision-making.
[5] In several countries including Australia and Canada, candidate selection is normally conducted by internal party processes at the constituency or electorate level.
[5] In Belgium, the Belgian Christian Social party set rules aimed at ensuring balanced preselection of Flemish and Francophone candidates.
For example, the Australian Human Rights Commissioner, Tim Wilson, resigned that office in February 2016 before nominating for the Liberal Party.
