Civic duty and turnout in the UK referendum on AV: What shapes the duty to vote?

This paper examines the question of what shapes a voter's sense of duty to vote. We begin with a standard model of turnout at the 2011 British electoral system referendum. We show that the respondent's assessment of whether it is a citizen's duty to vote on referendums adds substantial explanatory power to a basic model of turnout. From here we move to examine what drives that sense of duty. We find that assessments of duty are structured by evaluations of politics and politicians. Low interest in politics, low political efficacy, and low regard for politicians correspond with less support for the idea that citizens have a duty to vote on referendums and at other elections. These findings have implications for accounts of turnout decline that stress the effects of a public that is exposed to negative portraits of politics and politicians.
