How to win the UK referendum on the European constitution

Opinion polls suggest the UK Government faces an uphill task in winning the forthcoming referendum on the European Constitutional Treaty. This article provides a detailed analysis of the factors that are likely to decide the referendum outcome. Using recent survey data, we analyze the factors that influence individual-level support for the Constitutional Treaty. These results show that it is not only general attitudes towards European integration which are likely to play an important role, but also partisanship and satisfaction with the government. Given the low levels of information about the Constitution and the large number of undecided voters, the campaign itself will be crucial to the outcome. We argue that while information alone will not necessarily persuade voters, a successful campaign strategy by the yes-camp could make a decisive difference by motivating and informing voters, as well as setting the agenda for the debate.
