3 or 5 member multi-member voting districts determined by a geographic clustering algorithm using approval voting.

Honestly I am surprised that tackling a method of easily collecting approval votes hasn't been done yet.

Like even in the abstract "here is what a voting sheet would look like" that isn't meaningfully more complex.

To be clear I think it is a hard problem and so far is the biggest detractor to alternative voting schemes.

However given all that I agree with your point that it is a meaningful path forward.
