Although all were written with respect to politics of the moment, here on Election Day, 2018, the urgency of significant electoral reform remains. For instance, take the Fivethirtyeight.com forecast for the House. Using their “classic” forecast, we see that “Democrats are favored to win a majority of seats if they win the popular vote by at least 5.6 points”.
That’s right. Democrats could win the popular vote by more than FIVE percentage points and we could still have a Republican House seat majority. That would be a scandal of representation. No electoral system should be considered justified on democratic (or republican–note small initial letters) grounds if it is within the realm of realistic probability that a reversal of the voting plurality could occur even with a five-point edge for one party. (Their forecast gives Republicans about a 14% of retaining their seat majority; if they do so, it will almost certainly be without a plurality of the vote.)
It hardly matters whether the root of such an outcome would be gerrymandering (partisan-biased district-boundary drawing) or simply the geographic distribution of votes (i.e. Democrats running up huge margins in their safest seats while Republicans eke out many more close wins). Both causes are inherent to use of the single-seat plurality (or sometimes majority) electoral system.
Of course, it is easier, in principle, to fix the gerrymandering cause. And there are several such measures, along with other electoral-reform measures, on ballots around the country today. As I said in a post in 2005 opposing (with some reluctance) a measure in my state that was billed as terminating gerrymandering, these do not solve the fundamental problem, even though they would help.
In addition to almost totally ensuring that the party with the most votes also has the most seats, proportional representation would limit polarization, open up alternative dimensions of issue competition, and institutionalize a voice for the sort of anti-establishment sentiment that now only bursts forward in spasms of “radical middle” or “populist” voting.
Henry Droop made many of these points a century ago. I made variants of them a dozen or so years ago. And they remain relevant today. Literally today.
