What's wrong with DDs ranking people they really don't want to see elected below people they've neverAnd Debian Developers certainly do vote strategically in DPL elections, although they wouldn't call it that; they'd call it "ranking people they really don't want to see elected below wacko cranks and people they've never heard of before."
heard of before? (I don't know what a wacko crank is.)
Moreover, the lack of expressiveness of Condorcet makes is impossible to cast a ballot saying: "I think A and B are really good, with A just slightly better than B, while I think C and D are both pretty bad, and E and F are both terrible." In attempts to shoehorn this into Condorcet people do things like putting X between B and C or between D and E, but that only increases the expressive power slightly and also does not actually have the desired effect.
What? Who's X?
Even worse, Condorcet makes it impossible to say "dunno" about a candidate.
Since when?
