Support for the euro, political knowledge, and voting behavior in the 2001 and 2005 UK general elections

This article examines the effect of political knowledge on support for the euro and voting on the euro issue in the 2001 and 2005 UK general elections. Political knowledge increased support for the euro in 2001 but had no effect in 2005 and it conditioned the effect of the euro issue on vote choice in both elections. The effect of the euro issue on voting was stronger among knowledgeable voters, who were more likely to vote correctly on the issue by choosing a party closest to their own views on the euro. These findings demonstrate heterogeneity in voting on the euro issue in these elections and should motivate further inquiry into the role that political knowledge plays in conditioning voting behavior on European issues.
