Ranked choice has to precede a pluralistic system. We’ve had similar upheavals before, a long time ago (one presaged the civil war), but as long as we have first-past-the-post, it will always settle into two-party lock-in. But, and this is the good news, after the civil war, we had the second founding - a massive overhaul of the Constitution, for the better. If, in the aftermath of the death of the Republican party, we get another chance at that, (hopefully without all the killing), maybe we can enact ranked choice, eliminate the electoral college, ban gerrymandering, establish mandatory voting, add an enforced “none of the above” option to ballots, expand the Supreme Court, uncap the House of Reps limit, eliminate the senatorial land-vote in favor of proportional representation, get fully publicly funded elections, and and and am I asking too much? I just want a real democracy.
