[EM] General PR question (from Andy Jennings in 2011)

[Kathy Dopp]

Tony,

IMO, a better measure taking your approach, would be simply the sum of
the measures of individual voters' representation and electing the set
of candidates that maximizes this sum of representation measure.  In
fact, using such a summation measure would be, IMO, a good way to
compare the satisfaction of voters with various voting methods.

The problem with STV is that it would, in circumstances where there
are three strong candidates, often result in much less satisfaction of
voters according to the sum of individual voters' representation
measure than approval voting and many other voting methods, due to the
unfair way it treats different voters' ballots unequally, counting the
2nd and 3rd choices of some voters but not others due to its
sequential consideration and elimination method.
