Parties under stress: Realignment and dealignment in advanced industrial societies

The findings of a forthcoming study of electoral change in advanced industrial democracies are reviewed. These findings point to broad‐based processes of change that can be organised around two models ‐a social cleavage model of realignment and a functional model of dealignment. Both types of change are at work in most party systems. Surprisingly, their impact on future party system change is likely to be more reinforcing than contradictory in altering the context of party competition and moving parties further away from the responsible party model.
