I want to add something else to my argument: For normative reasons I consider the Borda Count to be an unsatisfactory election method. I have certain behavioral, strategic, and political criteria that Borda fails miserably (no method is perfect, but Borda gets a flat F while some methods gets C's and B's, even occasional A's). I'm interested in election methods as reforms to make our political system better. To that end, mathematics can be a useful tool for understanding different methods.
However, when a particular mode of analysis (as in analyze, not "analysis" in the mathematician's sense of "real analysis", "complex analysis", "functional analysis", etc.) keeps building toward the conclusion that "Borda rocks!" I have to conclude that this mode of analysis does not shed any light on questions that interest me. It may shed light on questions that interest Donald Saari, but it doesn't shed any light on questions that interest me. His method may be rigorous in the sense that it is self-consistent, all statements following as rigorous conclusions drawn from certain axioms, but it still isn't interesting. I realize that this may sound like a closed-minded approach: "It says something that I disagree with, therefore it must be wrong." Not quite. Although I haven't carefully read all that Saari has ever written, what I have read of Saari's work never answers any of my questions, and never provides any new considerations so compelling that I disregard my initial objections to Borda. It's kind of like Colin Powell's speech on Iraq: I have certain questions regarding national security and possible outcomes in Iraq. Powell didn't answer any of my questions, and what he did say didn't sound sufficiently compelling to take precedence over my unanswered questions. If he had come up with something so compelling that my other (still unanswered) objections were moot, I'd have changed my mind. (Not to drag too much politics into this list, but it seemed like a valid analogy.) Of course, not everybody shares my values and concerns. That's fine. Saari probably provides a lot of insights that interest other people. The democratic process will ultimately decide whether we use election methods that I like, that other people like, or the status quo.
