Does the left-right cleavage still structure citizen political behavio
r? What are the explanatory limits of cleavage politics? These questio
ns are examined in light of support for a contemporary far right party
, France's National Front. Though the predominance of former moderate
right voters testifies to the cleavage's enduring influence, the weigh
t of former left voters (especially those from the non-Communist left)
indicates the importance of citizen concern with crosscutting politic
al issues. Beyond voter movement from left and moderate right parties
alike, however, explanation of far right success must also attend to t
he contribution of previous non-voters as well as the emergence of a n
ew partisan loyalty.
