What is even more puzzling is Ms. Dopp's continued defense of
plurality
voting.
I chased this one a bit:
Did not see Kathy doing such.
Did not see her attacking Condorcet as if Plurality was better
than that (Condorcet interests me).
Stumbled on something Terry wrote Thu, 29 Jan 2009 15:37:01 -0500:
It seems suspect for a method to fail to elect a candidate
when a majority prefers that candidate to all other candidates.
Terry was referring to a single majority. In the IRV example below
there is no set of 7 voters who prefer A to all other candidates. Only
three voters, 1/4 of the total, prefer A to all other voters. The
example at hand was a Borda count in which there was such a majority
that fails to prevail:
51: A > C > B > D
5: C > B > D > A
23: B > C > D > A
21: D > C > B > A
Let's see:
3 A>B>C
4 B>A>C
5 C>A>B
A liked better than B? YES 8>4
A liked better than C? YES 7>5
A liked better than all other candidates? YES - B&C is all other.
