Public support for electoral reform: The role of electoral system experience

Abstract

What affects public support for electoral reform? How does experience with different electoral systems affect people's willingness to support electoral reform? Given the salience of changes to election rules even when they are passed via the legislature and the increasing use of referenda as alternative mechanisms for change, these questions are critical to understanding when electoral reform will occur. I argue that experience (specifically, with an electoral system similar to that under consideration) affects public opinion by reducing uncertainty about the likely effects of reform and thus affects support for reform (although the direction of the effect depends on partisan bias). Moreover, I argue that experience is most important in the absence of strong party cues. I leverage subnational electoral system variation in the United Kingdom and find that experience does affect support for reform — negative experiences decrease support for reform. The results have implications for the possibility of electoral reform in the UK and beyond.
