Elections without cues: The 1999 Australian republic referendum

In the November 1999 referendum on the republic, the Australian electorate was asked to make a complex, technical choice about the system of government, in the absence of clear partisan cues. How did voters resolve this dilemma? Although those in favour of replacing the Queen as head of state made up three-quarters of the electorate, they were divided on the method of election for the head of state, effectively resulting in three separate groups of voters. Four hypotheses are tested to explain voting in the referendum. The most important influence on voting was views about whether or not to sever the link with Britain, followed by the positive and negative aspects of the proposed change, and the cues presented by the leaders of the respective 'yes' and 'no' campaigns. Voters' knowledge of politics was also important. Overall, the interaction between compulsory voting and lack of political knowledge among large sections of the electorate served to divide republicans, and caused the proposition to fail. Pairing the republic with an unpopular change to the preamble of the Constitution also depressed the 'yes' vote.
