[EM] Why I think IRV isn't a serious alternative

[Dave Ketchum]

Topic is IRV vs Condorcet.

My point last time was that easy races are no challenge to either.

Now I concede that not all hard races are a challenge, but the few that IRV 
has handled do not guarantee that it will do all well, considering the 
opportunity for failure.
