Trident and public opinion:Evidence from the 2007 Scottish Election Study Rob Johns Department of Government University of Strathclyde robert.johns@strath.ac.uk
Abstract • Based on survey data collected around the time of the Scottish elections in 2007, this paper is about public opinion towards the British government’s decision to replace Trident. First, I investigate the impact of the campaign on attitudes to Trident, noting that a fairly stable aggregate picture conceals considerable change in opinions at the individual level. Evidence that many minds are not yet made up is obviously important for those – like us – seeking to influence public opinion on this issue, and so I look at the characteristics of those who are yet undecided. Then, turning to those respondents who did report an attitude, I assess the capacity of various social, demographic and political variables to predict whether those people are for or against Trident. Finally, I discuss the relationship between attitudes to Trident and party support, and present evidence that – despite the decision on Trident being a matter for the Westminster government – the issue had a marked impact on vote choice in the 2007 Scottish Parliament elections.
