Summarizer
Caucuses are meetings held by political parties at the county, district, or precinct level.01 Some caucuses choose candidates by secret ballot, while others require participants to divide themselves into groups according to the candidate they support. Undecided participants form their own group.0 The caucus system is a departure from the Westminster tradition, giving members of the upper house a say in the election of the party leader, who may become head of government. It also determines some matters of policy, parliamentary tactics, and disciplinary measures against disobedient MPs.2 The number of voters in each group determines how many delegates each candidate has won.1 Several states hold caucuses in the months leading up to a presidential election.0
