Issue competition in five countries: snakes in a tunnel
What determines the issue content of party competition? The extant literature is torn between issue ownership theories predicting contrasted partisan profiles and more strategic views of electoral platforms emphasizing parties’ incentives to converge on the priorities with the greatest payoffs. This chapter argues that parties are like snakes in tunnels: this metaphor conceptualizes parties’ incentives to emphasize contrasted issues to stay true to their identity and past priorities (the ‘snake’ component) as well as constraints exerted on those efforts by political opponents and context (the ‘tunnel’). Parties need to accommodate emerging problems and their competitors’ strategies, resulting in considerable cross-partisan overlap. Utilizing analyses of Comparative Agendas Project data on issue attention in party manifestos, plus qualitative observations on single electoral campaigns and how parties ‘steal’ issues from each other, the chapter discusses the potential implications of our observations for the way elections influence policies, a topic at the core of the next chapter.
