Attitudes Towards Divided Government and Ticket-splitting in Australia and the United States

Divided party government has become a frequent occurrence in both the United States and Australia in recent years. In the United States, Morris Fiorina has argued that this result is intentional on the part of the voters, who do not fully trust either party to govern by itself. We test this theory in both the United States and Australia by comparing the voting patterns of those who prefer divided versus united party government. It is hypothesised that Fiorina's theory will actually work better in Australia than in the United States, due to the presence of a strong party system as well as a voting system for the Australian Senate that facilitates strategic voting on behalf of small parties. Indeed, near-identical logistic regression models demonstrate that Australians' attitudes about divided government are a very significant predictor of straight-ticket voting even when a host of other factors is controlled for, whereas in the United States such attitudes are insignificant.
