I do not disagree that that kind of ballot can fail. If the Democrats had a very popular candidate, some voters might simply assume that they can vote for the Whig because surely the popular Democrat that they might have voted for is safe. Kind of like what happened recently in Alberta, where Labor won because the Right split between two competing parties. I would be inclined to offset my kind of system with four public tally days over a couple months, where voters could observe how it is breaking and submit a revision to their vote. The idea that voting must happen blindly may not be the ideal.
We only see the result of two-party dominance. If the system pulled its rigid support for the parties by eliminating the binary result, we would very likely see voters gravitating to other camps or becoming even more unpredictable.
And if Congress was fit with more than one big aisle, we would probably see more compromise and coöperation and less fuck-you-we-do-what-we-want.
It should be noted that every voting system has some situation where it gives a different result than it “should”. This was mathematically proven, and is called “Arrow’s impossibility theorem”. That said, some voting systems have failures more or less frequently than others, or of greater or lesser severity.
Well, that, and a presidency-by-sortition would be too noisy. You wouldn’t have the Law of Large Numbers evening out the wrinkles, and there’d be no check when the occasional crazy got elected.
I think that, for the most part, people want to be represented by politicians who consider the same issues important, and what issues people consider important will often track demographic traits (and for that matter, what issues people consider important can themselves be considered demographic traits). Granted, there are many demographic traits that I would consider wholly irrelevant in picking representation, and the fact that sortition would also balance those out is a useless (but harmless) feature. As for “who they want to be represented by”, that’s why I allow for a randomly-selected citizen to choose someone else to act as their representative.
That’s my point. You don’t have PR in the UK, and you have a system that rewards loyalty to party, which is the very defect that you attribute to PR.
All you’re saying there is that the UK system can be made to incentivize loyalty to local party, rather than loyalty to national party. It’s still loyalty to party.
Aberdeen Council is elected by proportional representation in multi-member constituencies using the single transferrable vote. Isn’t this rather an example that tells against your argument, rather than for it?
It’s certainly an improvement over the system mainly used in the UK, but it still suffers from the defect that 100% of the representation goes to one party, and 0% to all others.
