A. The plurality method can be put into a matrix, as follows. Example- 3
candidates, A, B, C. The first choice votes (and only votes) for each are--
1A 1B 1C
The first choice votes can be put into a matrix.
A X 1BA 1CA
B 1AB X 1CB
C 1AC 1BC X
The two amounts in each column are the same (i.e. 1AB= 1AC, 1BA= 1BC, 1CA=
1CB). Each one (1) can, of course, be dropped to produce the standard matrix.
B. With additional choices, the choice levels can be shown, as follows.
Standard 1, 2 and 3 ranking choices are made.
2B 2C 2A 2C 2A 2B
3C 3B 3C 3A 3B 3A
which produces the X over Y values of
2BC 2CB 2AC 2CA 2AB 2BA
Combining the same X over Y values produces (T= Total)-
1AB + 2AB= ABT
1AC + 2AC= ACT
1BA + 2BA= BAT
1BC + 2BC= BCT
1CA + 2CA= CAT
1CB + 2CB= CBT
The amounts are put into the standard X over Y matrix.
A X BA CA ART
B AB X CB BRT
C AC BC X CRT
CT ACT BCT CCT GT
RT= Row Totals, CT= Column Totals
GT= Grand Total
If there is a tie (such as AB>BA, BC>CB and CA>AC), then one or more of the
values can be the tie breaker.
C. The 3 election types (single executive/ judicial, multi- executive/
judicial, and legislative (proxy proportional representation)) can each be
deemed to be deemed variations of head to head contests ----
single executive/ judicial-- which of two candidates gets the most first
choice votes plus later choices from the other candidates where the voter has
one vote for one of the candidates,
multi (M)- executive/ judicial-- which of M plus 1 candidates gets the most
first choice votes plus later choices from the other candidates where the
voter has M votes (and one vote for each of the candidates),
legislative (S fixed seats) - which of S plus 1 candidates gets the most
first choice votes plus later choices from the other candidates where the
voter has one vote for one of the candidates.
