Change and Continuity in the Ideology of Australian Prime Ministers: The Governor-General's Speeches, 1946-2010

In Australian politics, narratives have developed around the ideological lineage of prime ministers from the same party so that, for example, Howard is often compared to Menzies and Hawke to Whitlam. In this article we examine the extent to which the ideology (left-right) of prime ministers from the same party has changed over time. We analyse the contents of speeches the Governor-General delivered at the opening of parliament between 1946 and 2010. We validate a number of narratives around the ideological lineage of prime ministers in relation to their party predecessors, and invalidate others, by analysing the speeches using the Comparative Manifestos Project coding scheme. This article also argues that parties do matter and shows how the addition of coding for ideology can complement the Policy Agendas Project method.
