For two decades researchers have been arguing whether profound changes were
taking place in electoral politics or not. Surprisingly little attention h
as been paid to party identification in the European debate. In Norway, par
ty identification has dropped dramatically since the mid-1980s. We hypothes
ize that the strong psychological ties between citizens and parties, descri
bed as party identification, have become a rare occurrence for several reas
ons. The intense debate over EU membership weakened the formation of party
identification in two periods linked to the referendums in 1972 and 1994, b
ut we also believe the observed decline in party identification to be a lon
g-term change linked to the fading of the old cleavages and the decline of
parties as mass organizations. The hypotheses have been tested on data from
the Norwegian Electoral Surveys and the Referendum Surveys from 1972 and 1
994. Although the hypotheses find support, alternative explanations cannot
be ruled out at this stage.
