Research on the voters of the extreme right inWestern Europe has become a minor industry, but relatively little attention has been paid to the twin question of why support for these parties is often unstable, and why the extreme right is so weak in many countries. Moreover, the findings from different studies often contradict each other. This article aims at providing a more comprehensive and satisfactory answer to this research problem by employing a broader database and a more adequate modeling strategy. The main finding is that while immigration and unemployment rates are important, their interaction with other political factors is much more complex than suggested by previous research. Moreover, persistent country effects prevail even if a whole host of individual and contextual variables is controlled for.
