I don't believe this satisfies the Condercet criterion either. Consider these rankings of preferences: 20% A ... 20% B ... 15% C ... 15% D C .

I don't believe this satisfies the Condercet criterion either. Consider these rankings of preferences: 20% A ... 20% B ... 15% C ... 15% D C ... 15% E C ... 15% F C ... In a two-round run-off, one of A or B will be elected, despite the fact that 60% of voters prefer C over either A or B.

And in the real world, people would second guess this, and enough people would tactic vote for C that it would't be a problem. "But then they can't vote for their prefered candidate which was the whole point" Well, some people can. D, E, F could still get a few percentage points. More importantly, I don't think we would see convergence to a 2-party system. Unless I am missing something, it looks like at least 3 parties could be sustained.
