Hoorcollege 7: Party Systems: Supply side Flashcards
Aside from cleavages, what can also influence a party system
- Electoral system
- How parties compete
Duverger argument
FPTP leads to two party and proportional systems to multi party. Not only institutional, but psychological (voting for a third party is useless).
Proportionality
Translation from votes to seats
Two different kinds of electoral systems
- Single member constituencies: FPTP, two round systems
- Mixed systems: proportional systems, closed and open lists
FPTP
- Single representative for a single constituency
- The candidate that wins the most votes in the constituency is the winner
Consequences of FPTP proportionality
- Highly disproportional because the votes for parties translate into the amount of seats in the constituency
- When there are less issues the level of disproportionality is lower
- There tends to be an underrepresentation of low geographically concentrated parties; bias results
- With fragmentation and the rise of new parties the voting system functions as a high threshold
Proportional open list
- High proportionality
- High number of political parties
- Very open party system
- Very open to changes in voters
- Fragmentation
- Difficult government formation
Proportional with majoritarian results/closed
- Ratio of votes to seats is low (not a lot of seats for amount of people)
- To prevent fragmentation
- Smaller parties less succesful nationally
- Regionally concentrated parties do better
What do electoral systems do?
Translate votes into seats. Important implications for which parties get into parliament and how cleavages are represented.
Two ways of counting parties
- Quantitative
- Qualitative
Quantitative approach
Give each party a weighted score according to their electoral results. How relevant these parties are according to their electoral results. Can be used to assess party fragmentation, see changes in number of effective parties.
Party competition as a way of counting
Need to look at how relevant a party is.
When is a party relevant?
- Coalition potential: come into a coalition
- Blackmail potential: prevent a coalition
What is important for party competition according to Sartori?
- the number of parties
- the nature of competition (centrifugal/centripetal)
- the degree of polarisation
The combination of important elements of how parties compete produces different party systems:
- Two party system: competition is towards the centre, the centre is the battleground for seats and votes (centripetal)
- Moderate pluralist systems: many parties with a limited degree of polarisation compete for the centre with alternating or different coalitions depending on outcome
- polarised pluralist systems: a multiparty system where party competition is defined by the extremes (anti-system parties). Communists and fascists made the party competition towards the extremes. Mainstream parties needed to radicalise to maintain votes. The centre is occupied by a party (centrifugal)
