The Waxenberg family's map went over the top. It was the best at illustrating the point about what you have to do to create competitive districts.
With this map, we sought to minimize population variances while maintaining reasonable adherence to compactness and other key principles. In order to bring all districts to a population of within a few hundred of the target, we had to split a few extra counties. We have generally treated county splits as a last resort, but it seemed the only way to achieve the desired result.
