Demassified Mass Parties or Overloaded Cadre Parties? The Impact of Parties on Electoral Outcome in Finland*

This article examines the frequently cited hypothesis of the changes in modern party organizations towards the catch-all model, and of the attempt of political parties to counter threats of electoral failure by intensifying membership support. The results indicate that in Finland former mass parties have been demassified and cadre parties have been overloaded. However, there are differences in party alignments and in the internal organizational structure of the parties that make a strict application of the catch-all concept problematic The findings also give evidence of a threat of declining electoral success that has implications for the membership support in the parties in very special situations. The threat from other parties seems to have only little or no effect on the membership figures. But when this threat is combined with a steady erosion in the traditional social bases of the parties, then the party response can be strong for the purpose of widening the electoral market by personal influence, as was the case with the rural Center party in Finland.
