type of ballot used. Maybe something like "Venzke Ratings"?
It has occurred to me that the method is similar in concept to "Runoff Without Elimination". This quickly led me to
realise that RWE could be simply improved by instead of candidates being permanently "shunted", we adopt Kevin's
mechanism of marking candidates (maybe temporarily) "not viable", and also we use Kevin's stopping rule (when all
but one candidate is marked "not viable").
"Inproved" RWE (Venzke CR/Approval adapted for plain ranked ballots):
Ranked ballots, equal preferences and truncation ok.
First iteration: Count the first preference votes and mark the candidate with the lowest tally as "not viable".
Reset the tallies to zero.
Second iteration: Each ballot contributes a vote each (no split votes) to their favourite candidate/s of those not marked
"not viable", and also to any marked "not viable" for whom they show equal or higher preference .Now mark the two
candidates with the lowest tallies as "not viable", and reset all tallies to zero.
And so on, each time marking as many candidates "not viable" as there have been iterations(inclusive). The tag expires if
it is not renewed at the next iteration. When all but one candidate is marked as "not viable" , then that candidate wins.
