I am responding to both Condorcet (which I see as useful for issues such
as ballot design) and EM (which will do best on election methods if they
are kept in one discussion).
There has been much debate over influencing results via strategy. You
have to be close to a tie for this to make a difference. Certainly you
need to avoid temptation in methods but, mostly:
Required plotting and secrecy is not practical in public elections.
Practical in some organizations - perhaps discussion of defenses
would deserve setting up a list for this.
The important public elections are multiprecinct and even multicounty.
Results from each precinct SHOULD BE understandable, publishable, and
addable for entire district via either published data or the same data
forwarded from the precincts (but NO forwarding of individual ballots as
some methods would require).
Write-ins must be supported by method:
Treat write-ins as a candidate - usually getting a total that says
no detail required. If needed, count the ballots.
Treat each different written name as a separate candidate. The
arrays used to count votes CAN be expanded as names are found, but it is
not practical to decide whether similar names are the same in the hurry of
Voters will indicate rank by number:
The same number indicates equal rank.
Different numbers indicate which is preferred.
The above DOES NOT require that each number must be used, with no
gaps - or prevent truncation via omitting numbers (and truncation of those
the voter chooses not to rank is PERMITTED).
The above does not prevent a counter from amending votes with a
pencil - a worthy topic for thought.
Voters adding other indications such as approval - forbidden by the
command to simplify.
Wv vs margins - debatable. I vote for wv, considering the 97 in 97>95
more significant than the 3 in 57>54.
Give A and B each .5 for A=B - debatable. I say yes for wv, advancing
each count the same amount for A=B and A=B as for A>B and B>A.
Introducing random numbers? I choke on these for all but exact ties - let
the voters decide. For exact ties, anything with equal odds is good
enough - even waking up one voter who did not vote.
