3 Electoral Systems Flashcards
Majoritarian systems
require the winning candidates to win a simple majority of 50%+1 or more of the valid votes
e.g. supplementary vote
Plurality systems
require the winning candidates to gain more votes than any other candidate
e.g. FPTP
Proportional systems
allocate the number of seats gained roughly in proportion to the percentage of the vote gained
e.g. additional members system, single transferable vote

FPTP
UK divided into 650 constituencies based on population (done by the Independent Boundary Commission and voted on by Parliament)
each constituency is represented by a single MP
voters cast their vote for the person they want to represent their constituency
the person with the most votes becomes MP
the party with the majority of MPs (at least 326 out of 650) is invited to form government by the monarch
Advantages of FPTP
simple, quick system which should encourage voter turnout and increase legitimacy of the resulting government
strong government with majority of MPs, allowing parties to carry out their manifestos
single representatives means a close party representative link and accountability
creates a 2 party system which keeps extremist parties from getting into power
Disadvantages of FPTP
results in wasted votes because only the candidate with the most takes the seat
winner’s bonus can give the government power in excess of the vote they received
2 party system leads to tactical voting, voters choosing the least bad of the two main parties
creates safe seats in which the value of an individual vote is reduced
AMS
voter casts two separate votes - the first for an MSP or MS to represent their constituency and second for a party to represent their region
Scotland is divided into 73 constituencies, Wales has 40. Constituency MSPs are elected using FPTP from the first vote cast
the second vote is used to elect regional MSPs in 8 large regions in Scotland, 5 in Wales. Using the d’Hondt formula takes the results of the constituency elections and votes cast in the region to allocate the remaining seats proportionally
Impacts of AMS
creates a multi-party system
creates minority or coalition governments
smaller parties have greater success in the regional vote, major parties do well in the constituency vote
growing success of nationalist parties in devolved Parliaments - SNP and Plaid Cymru
STV
NI is divided into 18 regions which each elect 5 MLAs. Multiple candidates from each party appear on the ballot paper
the voter ranks candidates in order of preference, ranking as many or as few as they would like - ordinal voting
the Droop quota is calculated
any candidates who reach the quota are awarded a seat, any votes above the quota are redistributed according to next preference, if a candidate now reaches the quota they also get a seat
if any seats remain but no one has reached the quota, the bottom candidate is eliminated and their votes redistributed by next preference. this is repeated till all seats are filled
STV impacts
creates a multi-party system
in NI the Good Friday Agreement (not STV) means the government resulting from an election must be power sharing, Both Sinn Fein and DUP must hold roles in government
smaller parties do better in the regional vote
SV
the voter has one vote but is able to identify a first and second choice on their ballot
all votes are cast and first choices are counted
if anyone has 50%+1 or more they are the winner and the election is over
if no one has 50%+1 all but the top 2 candidates are eliminated and their votes redistributed by second preference
someone will now have 50%+1 or more and they are the winner
SV impacts
creates a 2 party system
if used on a large scale, would result in a single party government with smaller parties having little chance to gain power
create safe seats if used for general elections
