I guess a lot of CWs wouldn’t be getting elected.

The best Condorcet methods don’t importantly fail FBC. A sincere CW can
only lose by offensive strategy, & the better Condorcet methods well-deter
offensive strategy. No need for any defensive strategy.

Was it you who once said that people would try offensive strategy? The
whole point of strategy is action based on an analysis of what the result
will be. It’s a strategist’s business to find that out first.

Anyway when it’s noticed to usually backfire…
