Euroskepticism in ParliamentaryCoalition Systems.

This paper examines how the European Union changes national-level politics, focusing on the role of Euroskeptic political parties. I argue that (1) Euroskeptic parties are less likely to participate in government coalitions than are Europhile parties; (2) parties with an elite-mass division over the EU will have a Europhile leadership and Euroskeptic masses; (3) when parties change their positions on the EU, they will be more Euroskeptic when in opposition and more Europhile when in government; and (4) parties that are extremist on non-EU dimensions are more likely to be Euroskeptic. These results will not be found in majoritarian political systems because they stem from the party coalition formation process. [ABSTRACT FROM AUTHOR]
