Electoral Systems
- First Past the Post
- It is a plurality
system so you
only have to get
more votes than
everyone else
- Helps maintain
a 2 party
system
- Produces
clear results
with
majorities
and
mandates
- Allows
swings
from
one
party
to
another
-
landslide
effect
- There is
a link
between
votes
cast
and
seats
gained
called
disproportionality
- Many
votes
are safe
seats
and it all
comes
down to
marginal
seats
- A party can get a lot of votes but no seats (UKIP, Green 2015)
- The Alternative Vote
- 1) Voters rank
all candidates in
order of
preference
- 2) First
preferences are
all counted and
if no one has a
50% majority
the bottom
candidate
drops out and
votes are
redistributed
- 3) This
goes on
until one
candidate
has
50%
of
the
votes
- AV ensures fewer wasted votes
- You can win of redistributed votes
making you least unpopular candidate
- Favours larger parties
- Supplementary Vote
- To win you
must get 50%
of the vote
- Voters have a
first and
second
preference
- If the first
preferences don't
give a win. All
candidates but
top 2 drop out
- Their second preferences are
then redistributed to the
remaining two candidates to
bring about a result
- SV is simpler than AV and is easy to understand
- Could discourage small parties in favour of tactical voting
- Regional Party List
- Country is divided into large constituencies
with lists of candidates provided by political
parties
- The parties rank their own candidates in order
of their own preference. Voters vote for parties
and seats are allocated off the list in direct
proportion to votes cast
- It is fair to all parties regardless of their size and popularity
- A lot of small parties could lead a very unstable government
- Single Transferrable Vote
- Large constituencies with up to 7 seats each
- Each party can have 7 candidates
- Seats allocated on a quote and extra
votes go to other preferences
- Capable of achieving highly proportional outcomes
- Can vary hugely based on the basis of the party system
- Additional Member System
- Voters, have two votes - "one plus one"
- First votes are cast in single member constituencies in the
traditional way, but the second vote is counted seperately
towards a party list
- Two types of representative are
elected - one from local
constituency and others
nominated by political parties,
according to the "plus one" vote
cast
- Balances the need for constituency representation against the need for electoral fairness
- The retention of single-member constituencies reduces likelihood of high levels of proportionality
