The efficiency gap as a formula isn’t particularly of note, what won the Wisconsin case was the approximately ~70 pages of further statistical analysis that Simon Jackman performed (available here).
The UK has a pretty poor efficiency gap despite having a truly independent boundary commission. Voting distribution doesn’t sync neatly with population and spatial distribution and an efficiency gap itself is not evidence of gerrymandering.
Efficiency gaps are a hallmark of single member first-past-the-post systems more than they are of gerrymandering (hence why Jackman’s research shows almost all districts to be ‘gerrymandered’).
Using a formula that breaks down in edge cases isn’t electoral reform, and electoral reform is the only thing that removes inefficiency and unfairness from the electoral system you guys use.
in 2016, the Democrats took control of both houses in Nevada.
Now the GOP is trying to get a recall election going… because of… reasons?
As far as I have seen, there’s no legitimate reason for a recall. There’s no suggestion that the election was unfair, or that anyone has done anything wrong meriting a recall.
One thing that Democrats will need to do here, is evenly apply anti gerrymandering rules going forward once this is settled. Maryland is one of the worst cases, and it’s in favor of Democrats. They are going to have to be honest about that and allow it to be fixed as well, even though it will hurt them politically to do so.
