The rise of the radical right is open to multiple interpretations. The question addressed in this paper is whether many of these parties have fostered an enduring social base among core voters and, if so, which social sectors are most likely to support them. The first part discusses the alternative theoretical frameworks provided by the classic accounts of the 1950s and 1960s, the "new social cleavage" thesis common during the last decade, and the theory of partisan dealignment. Then, it compares evidence to analyze rival hypotheses about the social basis of the radical right vote across fifteen nations, using data drawn from the European Social Survey, 2002, and the Comparative Study of Electoral Systems, 1996-2001. The second part focuses upon the role of socioeconomic indicators, while the third part considers the enduring gender gap and patterns of generational support. The conclusion considers the implications of these results for understand ing the basis of radical right popularity, and for the stability and longevity of these parties.
