I'm afraid I don't understand your examples at all. The "no first preferences" example is so extreme I would not consider it realistic. But, of course, if it were possible to elect a "no first preferences" candidate as the Condorcet winner, such a result would completely unacceptable politically and the consequences would be disastrous. The two situations I had in mind were: Democrat candidate D; Republican candidate R; "centrist" candidate M Election 1 35% D>M; 33% R>M; 32% M Election 2 48% D>M; 47% R>M; 5% M M is the Condorcet winner in both elections, but the political consequences of the two results would be very different. My own view is that the result of the first election would be acceptable, but the result of the second election would be unacceptable to the electorate as well as to the partisan politicians (who cannot be ignored completely!). If such an outcome is possible with a particular voting system (as it is with Condorcet), that voting system will not be adopted for public elections. James No virus found in this outgoing message.
