The biggest gap between election researchers and election administrators or reformers is in their appreciation of Condorcet's rule. Despite praise from researchers, Condorcet's rule is not used by any major jurisdiction. Reps don't want to change the rules they have mastered. They like safe seats that old rules create. Even in list PR there are many safe seats.
Few activists push for anything new.
Reps and activists enjoy battling for winner take all victories. The difference between the winner and runner-up by plurality or runoff is the difference between the 2 parties. Condorcet elections and legislation help the broad middle. They do not offer thrilling victories or defeats. But Condorcet's rule could be used frequently for decisions by any council, including private organizations and schools, where this change should begin.
