Markus - this was NOT a proposal made by ME. I was merely speculating (following earlier comments by others) that IF a solution could be found to the weak winner problem and IF a simple solution could be agreed to deal with (rare) cycles, then perhaps Condorcet might be considered a contender for public elections in a way that it has not been for the past 220 years. > I don't think that it makes much sense to try to find > a Condorcet method that looks as much as possible like > IRV or as much as possible like Borda.

IRV has a significant political defect, but the empirical evidence is that electors and politicians will accept IRV despite that defect. So far as I am concerned, Borda is out of the window. Leaving cycles to one side, the problem for Condorcet remains that there is no "Condorcet solution" to the weak winner problem, or at least, I've never seen one suggested by any Condorcet advocate. Indeed, it has previously been impossible to get any advocate of Condorcet even to acknowledge that the weak winner might be a real POLITICAL problem. A similar political problem would confront any other voting system that would allow a "weak winner" to come through. It is one thing to discuss voting systems in a theoretical vacuum, it is quite another to achieve practical reform in the real world. Theoretical discussion is desirable and necessary, but right now, practical reform of the voting system is more urgent, and in more countries of the world than I like to think about.
