Referendums function in determining public opinion on specific issues by allowing citizens to vote directly on proposed policies or constitutional changes. This direct form of democracy provides an opportunity for voters to express their preferences outside of traditional representative processes. The results of referendums can create significant political implications, influencing legislative agendas and party positions. They can also serve as barometers of public sentiment, helping elected officials gauge community priorities and engage with constituents on key issues, ultimately enhancing participatory governance.
