Democracy is an abstract and murky concept. This is particularly apparent in the wide variety of beliefs about democracy held by publics around the globe. Within democracies, political parties often define and name themselves with reference to a particular understanding of democracy. This article focuses on this partisan division in understanding democracy. We suggest that parties will attract those who share similar beliefs about democracy. Specifically, we look at whether differences in beliefs about democracy predict party support in the United States. Examining the responses of US participants to the fifth wave of the World Values Survey, we find that differences on a number of "essential" aspects of democracy among individuals predict vote intent (and party identification). Those more likely to understand democracy as a form of government that promotes civil liberties and the redistribution of wealth to protect the vulnerable are more likely to vote Democrat. Those who report stronger associations between democracy and both religious interpretation of laws and severe punishment of criminals are more likely to vote Republican. This research reinforces the idea that policy differences between the two main parties in the United States may derive from different understandings of the role of government in society.
