You just took away my right to vote.
You say I could have voted for C by voting for (A>C>B) 1/1/0 (But if I did
that I can't vote for A over B).
With my vote of (A>C>B) of 10/1/0 I am saying that I do have preference for
C over B.
With Approval voting you are not allowing me to vote for a candidates that I
like better than another.
You also took away Clay's right to vote.
Clay can vote (A>B>C) 1/1/0 for A over C and B over C but you are saying
(with approval) that he can not vote for A over B.
He also indicated a preference of A over B with (10/9/0).
(assuming 4 candidates(A/B/C/D))
Now Plurality voting is limited to the following:
(1/0/0/0) or (0/1/0/0) or --- to (0/0/0/1)
Approval voting is limited to the following:
(0/0/0/0) or (1/0/0/0) or (1/1/0/0) or --- (1/1/1/1)
This is clearly better than Plurality voting. You have a lot more chances
to express you opinions
Preference voting is limited to the following:
Voting for A>B (1/0) or (0/1), and for A>C (1/0) or (0/1) and ---- etc.
In Pure Preference voting you have a ranking of (A/B/C/D) states only that
you prefer A>B and A>D and they are treated the same.
This method clearly provides more options for the votes than Approval
You may "Approve" of A and B but you still can have a preference of A over B
It also encompasses Approval voting if A=B (1/1) voting is allowed
A problem with Preference voting is that it does not always come up with a
Range voting is limited to the following:
(10/x/y/z) for A/B/C/D or any other combination (were x/y/z =< 10 and >= 0)
This method allows the voter to "Quantify" his or her Preferences. A>B
(10/9),--, or 10/0)
There are different forms of range voting, you could used 10 but you could
use 100 or 3 (3/2/1/0)
Range voting provides the maximum (or closes to it) flexibility (options)
for the voter.
Range voting however does add a lot more complexities to the voting process,
this makes it more difficult to see the impact of ones vote.
And there may be the Problem of adding individual quantified preferences.
A question voters need to ask is "how much added complexities do they want".
Plurality has been with us for a couple of hundred years.
If you ask voters to change to any of the other methods above most would say
"No way- all I want to do is Vote"
