What defines a proportional electoral system?

It allocates seats to parties in close relation to their share of the votes cast, usually through multi-member constituencies or a party list.

Explain how a candidate can win a seat under first-past-the-post with well under half the votes.

Only a plurality is required, so where several candidates split the vote the winner needs merely more votes than any single rival, not an overall majority.

What is a wasted vote?

It is a vote that contributes nothing to the outcome, either cast for a losing candidate or piled up beyond the number the winner needed.

A safe seat is a constituency where one party's majority is so large that the same party is expected to win at every election.

1
What is a majoritarian electoral system?
Model answer
One designed to manufacture a decisive winner and single-party government in single-member seats, either by requiring a majority of the votes still in the count after preferences are transferred, as AV and SV do, or by awarding the seat on a simple plurality, as first-past-the-post does.
2
What defines a proportional electoral system?
Model answer
It allocates seats to parties in close relation to their share of the votes cast, usually through multi-member constituencies or a party list.
3
Which system is used to elect the House of Commons?
Model answer
First-past-the-post, a single-member plurality system in which each constituency returns the candidate with the most votes.
4

Only a plurality is required, so where several candidates split the vote the winner needs merely more votes than any single rival, not an overall majority.
