| - | == Proposal: Single Transferable Vote ==

| - |
| |
| - | Notation:
| |
| - | * N seats available
| |
| - | * C candidates running
| |
| - | * T total valid votes cast in the election
| |
| - | * Q (the quota) = floor(T/(N+1) + 1)

| - | [http://en.wikipedia.org/wiki/Single_transferable_vote Single transferable vote] is the voting system used in Ireland's general elections, with multi-seat constituencies resembling a Maemo Community Council vote - there are N places and C candidates, with C > N. There is an added advantage of having [http://stv.sourceforge.net/ software available to count STV].
| |
| - |
| |
| - | The voting system is simple from the voter's point of view - you vote in order of preference for one or more of the candidates. If you only have a first preference, you vote only 1 for your choice. If you have a second preference, you give him number 2, and you continue like this down the ballot, as far as you care to go.
| |
| - |
| |
| - | Counting is also quite simple. We first count all the number 1 votes, and rank the candidates in order. If any candidates have more than T/(N+1) votes, they are deemed elected. Their surplus votes (the votes over the quota Q) are redistributed according to the weighings of their second preferences.
| |
| - |
| |
| - | If no-one has been deemed elected, or all surpluses have been distributed, the candidate with the least first preferences is eliminated, and his votes are redistributed according to the second preference.
| |
| - |
| |
| - | This process is repeated until N candidates are deemed elected, or until there are only 2 unelected candidates remaining. In this situation, the candidate with the highest number of votes is deemed elected without having reached the quota.
| |
| - |
| |
| - | A simple example will illustrate:
| |
| - |
| |
| - | 4 candidates (A, B, C), 2 seats, 11 votes, the quota is thus 4 votes.
| |
| - |
| |
| - | # A, B
| |
| - | # A, C
| |
| - | # A
| |
| - | # A, B, C
| |
| - | # B, C
| |
| - | # B, A
| |
| - | # B, C
| |
| - | # C
| |
| - | # C, A
| |
| - | # C
| |
| - | # D, C
| |
| - |
| |
| - | 1st count:
| |
| - | * A: 4
| |
| - | * B: 3
| |
| - | * C: 3
| |
| - | * D: 1
| |
| - |
| |
| - | A is deemed elected, and D is eliminated.
| |
| - |
| |
| - | D's 2nd preferences give 1 vote to C.
| |
| - |
| |
| - | 2nd count:
| |
| - | * A: 4
| |
| - | * B: 3
| |
| - | * C: 4
| |
| - |
| |
| - | A and C are deemed elected.
