Implications of Examples in Plurality Systems
• Voter support for small parties underrepresented in seats.
• Best for small parties to focus on winning support in select regions.
• Majority governments the norm.

PR Systems
• How the system rates:–Proportionality: Excellent
–Voter Choice: Bad
–Responsibility to constituency: Bad
Preferential Voting Systems
• Voters indicate intensity of preferences for different candidates by rank-ordering them on ballot.
Preferential Voting:Single Transferable Vote (STV)
• Malta, Ireland, Australian Senate.
• More complicated system:–Parties have multiple
candidates per constituency.–Voters number rank order of
candidate preferences.
Preferential Voting: Single Transferable Vote (STV)
• “Transferable” vote:–If #1 vote is useless, vote
transferred to next-choice candidate.
Preferential Voting: Single Transferable Vote (STV)
• This was the system recommended for BC by the recent BC Citizens’ Assembly.
• Referendum on question held May 17, 2005.
Preferential Voting: Single Transferable Vote (STV)
• How the system rates:–Proportionality: Excellent
–Voter Choice: Excellent
–Responsibility to constituency: Moderately Good
Preferential Voting: Alternative Vote
• Australian House of Reps, Fiji.• Rank order candidates in single-
member districts. Candidate wins through gaining “majority” of votes.
• Worse for proportionality than STV or PR.
• Better for voter choice, constituency representation.
NON-Preferential Voting: Single Non-Transferable Vote
• Multiple representatives elected per constituency, but voters only cast 1 vote choice.
• Japan (until 1994).
• Taiwan.
