[EM] STV and weighted positional methods

[Dave Ketchum]

The war here is over IRV/STV, which Kathy attacks, Terry defends, and I 
agree that kathy should win.

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.

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.

IRV elects B!
Condorcet elects A.
