electoral systems Flashcards
where is additional member system used
scotland, wales, greater london assembly.
how does the additional member system work
voters are given two votes: for constituency and for regional MP (party appoints not member)
AMS +
+more choice, voters have more choice when they choose a local representative and allows more flexibility in choosing parties
+fairer to all parties & more proportional eg under FPTP in 1997 the Conservative party won 0 seats in scotland and in 1999 under AMS they won 18
AMS -
-2 types of membership, inequality between especially in Scotland
-closed list system is used, party leadership ranks candidates. this is undemocratic as nobody has voted for the member
-more difficult to understand.
where is the single transferrable vote used
in the northern irish assembly
what type of system is STV
pluralist
how does STV work
voters rank 5 candidates and the candidates need to meet a threshold and the remaining votes are redistributed.
STV +
+close correlation between votes and seats
+smaller parties can grow
+voters have a lot more choice - 5 instead of 1
+ creates coalition governments which enable representation of 2+ communities which was essential in ending 30 years of NI violence
STV -
-in large, multi-member constituencies, MP-constituency link may be weakened
-coalition creation can cause chaos => presumes the two parties can cooperate. 2022 Stormont was placed on a 24 month hiatus during unsuccessful post-brexit negotiations and was left to be run by civil servants
-reduced legitimacy of MPs as there is a 1st winner and a 5th winner - clear disparity in support.
-hard to understand and complex
evidence that STV doesnt enhance democracy
in 2022 the power-sharing govt (stormont) collapsed after post-brexit negotiations. the DUP blocked the assembly so it ceased to operate for 24 months. this left unelected civil servants to run NI which hasn’t enhanced democracy.
results of STV in 2022
Sinn Fein 29%
DUP 21.3%
Alliance Party 13.5%
where is Supplimentary Vote used
london mayor elections and police & crime commissioner elections
what is supplimentary vote
each voter is allowed a 1st and 2nd preference and any candidate who gains more than 50% of the 1st preference is automatically elected. if this doesnt happen all candidates but the top 2 are eliminated and 2nd preference votes for these two are counted
SV +
+ensures broad support for the winner. Labour Sadiq Khan elected mayor in 2016 had the largest personal mandate: 44% of 1st and 66% of 2nd
+allows independent candidates to win -> 12 out of 40 police and crime commissioners in 2012 were independent
+relatively simple
SV -
-not proportional as one individual is allowed into power VS STV where 5 are allowed in
-winner doesnt need an absolute majority. = less legitimacy
