Week 3: Electoral system Flashcards
Electoral integrity
the extent to which elections meet international standards for fairness and transparency
what are the three main sub-systems in electoral system families
- Majoritarian: Plurality, absolute majority
- Proportional: List PR, Single transferable
- Mixed: Independent, dependent
What is a plurality electoral system?
a candidate wins by receiving more votes than any other opponent, even without a majority
what is an absolute majority system?
a candidate must receive more than half of the votes to win
What is proportional representation(PR) system and why might it be better than majoritarian system?
- ensures that political parties are represented in parliament in proportion to the votes they receive
- represents the diversity of voter preferences more accurately
What are the two sub-systems in the PR system?
- List PR: parties present candidate lists, and seats are allocated proportionally
- Single Transferable Vote (STV): voters rank candidates, and voters are transferred until all seats are filled, giving more voter choice and limiting party control
What are the three sub-types within the majoritarian plurality system and what type of district do each system exists in?
- Single-member district plurality (SMDP): single-member district
- Single nontransferable vote (SNTV): multi-member district - allows more chances for smaller parties as votes can be concentrated
- Block vote: Multi-member district
What are the three main sub-types of absolute majority system?
- Alternative (AV): voter rank candidates in order of preference, lowest member eliminated, votes redistributed on the next preferences until one candidate has a majority
- Two-Round system (TRS) - majority run-off: two rounds of voting, only the top two candidates from the first round compete in the second round
- Two-Round system (TRS) - majority-plurality: similar to majority run-off but more than two candidates can compete in the second round
In what type of district is PR system used in?
- only in multi-member districts
- produce a proportional translation of votes into seats
- political parties are important in this system
what are two subcategories within proportional system?
- List PR: parties create list of candidates, voters vote for a party rather than individual candidates -> seats allocated based on their share of votes -> candidates are taken from the party lists in order
- Single Transferable Vote (STV): voters rank in order of preference -> a candidate must reach a quota of votes to be elected, votes exceeding a candidate’s quota are transferred to the next preference on those ballots -> lowest-ranked candidates are eliminated and votes are redistributed -> limits party control over who gets elected
what are the two formula methods in the List PR system?
Quota (Hare, Droop) method and divisor (D’Hondt) method
How does higher electoral threshold help reduce proportionality?
They set a minimum percentage of votes that a party must achieve to gain representation in the legislature. If the threshold is high, smaller parties with lower levels of support are excluded from winning seats, even if their vote share would have otherwise entitled them to representation under a purely proportional system.
How does higher electoral threshold help prevent fractionalisation
Parties with similar ideologies are incentivized to merge or form alliances to surpass the threshold. This leads to fewer, larger parties rather than many small ones, which can dilute the vote.
what is fractionalisation
when political system is divided into many small political parties to allow even very small parties to win seats, which can make the parliament very fragmented
what is the downside of electoral thresholds?
cause disproportionality -> more votes are wasted (votes for parties that don’t reach the thresholds)
