Our electoral rules stink. Let’s change them.
Here’s the bottom line. Our single-member, winner-take-all approach to elections might have worked okay during a period of low polarization, when parties were overlapping coalitions, when more places had genuine two-party competition, and when voters were sometimes willing to support candidates from the other party.
But those things are in the past now. Our electoral rules are now gasoline for the current conflagration of partisan polarization. Because the polarization is primarily ethnocultural and therefore geographical, congressional districts and most states are safe for one party or the other. But in almost every national election, the balance of power in Washington is up for grabs.
I have been meaning to start this topic for a while and some people have asked for it. I finally ran across this vox article about some of the changes being proposed now that could actually move our system toward this.
