Thanks for your comments. Overall, I think our views are pretty
parallel -- certainly we're working for the same thing. I think I just
disagree with your interpretation of the situation on a couple of
relatively minor points:

Actually, I'm saying the inverse. My impression is that Duverger's Law
and the like imply:
* plurality primarily causes two strong parties to emerge
* secondarily, exacerbates tension between parties
As long as we have single-winner elections, and the need for majority
coalitions to approve bills in the legislature, I think we'll have and

Sure, I agree that one reason for their existence will diminish, but
I'm not so convinced that's the primary reason we have parties. Does
anyone know of examples or theorems which bear on that?

Perhaps this is why we look at it differently. You see election reform
inevitably pushing parties towards the center. My perspective is that
party ideologues would fight to the death to prevent that, leading
ultimately to split parties --- or, worse, realize it in advance and
torpedo efforts at reform. And my fear is that the
ideologically-driven factions would be better organized and thus more
effective than an amorphous centrist majority.
Sure, over time the tide of history favors rational solutions over
denial, but sufficiently ideological denial can slow progress for

Actually, I think of that as a symptom more than a cause. I guess I
subscribe, at least in part, to the "culture war" hypothesis that
political polarization is driven, at a deep emotional level, by
conflicting world views about right and wrong. I fully agree that
this division is both exacerbated and enabled by plurality, but I think
it also needs to be attacked at the roots.

Fair enough. I'm a big believer in election reform, but I stop short of
considering it either 100% necessary or 100% sufficient. But, its
close enough that I think it worthwhile, and admire those who put their
whole effort behind it.
