Kevin,
The question of the precise ranking of  the worst single-winner methods
doesn't interest me very much. I just mentioned it as a method in use with
absurd arbitrary features/restrictions that is dominated (in terms of useful 
criterion 
compliances) by IRV.

To reluctantly answer your question I suppose it isn't worse than FPP  and
is probably worse than Approval.

I'd be much more interested in your reaction to my recent "Range-Approval
hybrid" suggested methods, which after all use the concept of  "Approval
Opposition" which you invented.

Antiplurality is just a race to nominate as many candidates as possible
so that none of them get any votes.

I don't see how this is "very bad." I could see how you might think it
is easily improved. But is this method better or worse than Approval? Is 
it better or worse than FPP?

Just like Antiplurality.

[EM] Worst Voting Method

2008-10-15 Thread Chris Benham
I don't see antiplurality as much worse than FPP.

Antiplurality  (vote against one, candidate with fewest votes wins) meets
Majority Loser  and  Strong Favourite  Betrayal.

Very bad is the Supplementary Vote used to elect some mayors in the 
UK.   It is like the Contingent Vote  (one trip to the polls TTR) except
voters are only allowed to rank 2 candidates.

Borda Voting is also very bad.  It fails  Majority Favourite and  "Rich Party"
(meaning that it fails Clone-Loser in a way that advantages factions who field
more candidates).
