Electoral Systems Flashcards
What is another name for first past the post system
Plurality system
What are the main features of the first past the post system
Country is divided into constituencies
Each constituency returns one MP
At elections each party presents one candidate
The winner of the election is the candidate who wins more votes than any other candidate (plurality)
It is not necessary to win an overall majority to win a seat
What are the outcomes of using first past the post system
Many seats are safe seats
Usually a single party wins an overall majority (but this is becoming less certain 2010/2017)
Small parties have little chance of winning seats
Associated with 2 party system
As each party only has one candidate in each seat the system favours “safe” candidates ie less diversity
What is a marginal seat
A constituency where more than one party has a realistic chance of winning
What is a safe seat
Where one party is so dominant in the constituency that it is unthinkable that it would lose
How do elections enhance democracy
mandate - gives government legitimacy
Accountability - outgoing government held accountable for their actions
Representation - constituent views are represented
What is the additional member system also known as
Hybrid system
What is the plurality system also known as
First past the post
Which regions of the uk uses the additional member system
Scottish parliament
Welsh assembly
Greater London assembly
Why is it called the additional member/hybrid system
It is a hybrid between first past the post and proportional representation
How does the AMS work
2/3 of seats first past the post
1/3 elected on basis of closed regional list voting
What is closed regional list voting
Country divided into regions
Each party offers a list of candidates for each region
Voters have 2 votes - one for constituency and one for the party lists
Seats are added to each party in the list system in proportion to votes cast
The more votes the more seats
What is the Variable top up system
Device used in the AMS where parties most discriminated against in the constituency system are awarded additional seats in the list system to compensate
Why might variable top up be used
To make the system more proportional
What is the variable top up method also known as
D’Hont method
Name a party what would benefit from the use of the variable top up system
Greens
UKIP
What are the outcomes of the AMS
Tends to be approximately proportional to the votes cast
There are still many safe constituency seats so few violent swings
Voters have 2 votes and some “split the ticket”
Small parties can win seats through the list system even though they would not win constituencies
What is the single transferable vote system also known as
Proportional representation
Which uk elections use the STV (single transferable vote) system
Northern Ireland
Scottish local government
How does STV work
6 seats in each constituency
Each party can put up as many candidates as seats (so max 6)
Voters put candidates in order using a number (1,2 etc)
At the count an electoral quota is calculated.
All first preferences are counted and all who achieve quota are elected
After this it becomes complex - basically the 2nd and subsequent preferences for elected candidates are added to other candidates totals and if they reach the quota then they are elected
Repeat til 6 are elected
How is an electoral quota calculated
Take the total number of votes cast and divide by the number of available seats plus 1 and then adding 1 to give the final result
What are the main outcomes of the Single transferable vote system
Overall outcome largely proportional to 1st preference votes
Results in a multi party system
Small parties have a chance of winning seats
As voters can discriminate between all candidates and have many votes leads to diversity
How might Proportional representation affect proportionality
Pr gives more proportional outcomes than first past the post
How does proportional representation favour voter choice
Both STV (single transferable vote) and AMS (additional member system) give voters more than one vote
How does Proportional representation favour equal value of votes
Under pure PR systems all votes count equally
