I did this exercise by the way having no idea what it would portend. I never studied the CA CD map before. It was interesting since I by and large know the communities so well, and it was interesting to parse the changes from what the lay of the land was 20-30 years ago. Times have changed. My former precinct in Laguna Niguel since 2012 has moved about 15 PVI points to the Dems. Mittens carried it by 20 points, and Trump 2020 lost it by 10 points.
