Russ, I hesitate to respond to this, as I get the impression you just want to oppose all of Mike Ossipoff's ideas.

Your SFC is pretty absurd. It says that the loser of the strongest contest (by margins) can't win if that loss is to the CW. Mike's SFC says a majority of the voters don't need to do anything fancy to elect the CW. I can't see what or to whom your criterion makes a guarantee. > If you argue for wv, you are claiming that a 51-49 victory is "stronger" > than a 49-0 victory. Common sense tells us that's nonsense.

You can't toss out 51-49 over 49-0 without making guesses about the sentiments of the abstaining voters in the latter contest. > As Blake pointed out, we can think of truncated votes as more or less > equivalent to the same votes completed with random rankings.
