In the Rules of Procedure revision that I sent a few days ago, there
are several options to one of the voting stages in the selection of
the At-Large Director. The RoP revision group did not reach unanimity
on which option to pick (largely because of the deadline required to
sent the revision to the ALAC to allow us to approve the revisions in
Helsinki).
The options have to do with the reduction of three candidates to two.
In the optimal case, one of the three candidates will have fewer
votes (or first preference votes) and will be dropped, resulting in
two candidates being left. The difficulty arises if the two
candidates tie for last place, but with the leading candidate not
receiving an absolute majority of votes needed to be declared the
final winner.
Option 1: Re-run the entire three-way election, with the hope that
some positions may have changed. This would be done just once. If the
second vote results in a tie for the last position (even if it is not
the same pair as the first time), one of those tied is eliminated
based on a verifiable random selection. The down side of this method
is that no one may alter their vote and we would have to use a random
selection.
Option 2: Have a run-off vote between the two tied candidates. If the
results between the two is tied, a verifiable random selection would
be used to eliminate one of them. The down side of this option is
something called "strategic voting". Those electors who originally
voted for the leading candidate (the one not in this runoff) may not
vote for the person they prefer, but could vote for the one they
perceive as the weakest opponent to their preferred candidate.
Option 3: There will be no 2nd vote. One of the two tied candidates
will be dropped based on a verifiable random selection.
Option 4: Use the same STV voting as would be used in the first round
(to narrow the slate down to three). The BigPulse STV system will
always eliminate one candidate, but if it must resort to a random
selection, it would be internal to the voting system and would not be
verifiable (ie it would have to be trusted to have used a truly
random selection.
Since the ALAC will have to decide on a which option to use, it would
be good to begin the discussion now and not wait for Helsinki.
