majoritarian ES
elections take place in single member district. there’s one MP from that electoral district.
R1: 2+ candidate options if s.o gets 50% elected
R2: top 2 candidates
majoritarian ES leads to..
electoral coalition formation
proportional representation ES
elections take place in multi member districts. seats are allocated in a proportion to the received votes. ( % votes => % seats)
proportional representation differs based on…. (3)
- degree of choice of candidate
- level of threshold
- formula of seat allocation
degree of choice of candidate in PR systems (3)
- closed list: only party choice not candidate
- semi-open: presented with multiple candidates according to popularity
- single transferable vote: you rank candidates acc to your preferences.
plurality system (first past the post)
voters vote for candidates- they need to get more than anyone else- not a majority
mixed system
allows voters to choose individual candidates in single member constituencies and also choose for party lists
2 types of mixed systems
- mixed member majoritarian: 2 seperate elections determined by SMP and PR
- mixed member proportional: PR seats are used to adjust the total number of seats.
3 major consequences of electoral systems
- proportionality
- party systems
- minority representation
proportionality as a major consequence
- plurality systems: if all candidates get similar amounts of votes the results aren’t representative.
- pr: if they have a high threshold- it isn’t representative, also high level of proportionality can cause instability (hung parliament)
duverger law
countries with a majoritarian system have a two party system
a. mechanical: how the system translates votes into seats
b. voters thinking if they vote to a small party, their vote doesn’t matter
problems with duverger law (2)
party system may cause electoral system
if a parys votes are concentrated in a region- this doesn’t matter
minority representation as a consequence…
plurality: you only put forward a candidate that appeals to the medium voter because you have one chance
pr: you can create balance tickets.
ES manipulations in majoritarian systems (2)
a. malapportionment: deliberately ignoring the spontaneous changes in the composition of your districts.
b. gerrymandering: redrawing borders
