Not to be unsympathetic, but sometimes it's more of a compromise than a mistake. I notice this report has a dozen or so such charts. Perhaps someone thought there was value in using the same order throughout and didn't want to introduce an overall ranking.

Pleased to discover the Atlas of Historical County Boundaries with shapefiles to extract Georgia counties circa 1899. Now I can try a recreation of Du Bois's map. Projection is different, but I think I got the data right.

I tried it with a trivariate CMY gradient version of the soda map -- note desaturated areas in the west where there was little data. Pushing it but not terrible.

From a perspective, the connected lines don't work so well for me between presidents. The transition line is almost entirely in the preceding president's region. Maybe a step line, or a line break?

Thanks for the detailed write-up. This technique will be on my mind whenever I see a dual-axis chart in the wild.

The article suggests the group is really Hispanics, but that the Asians often follow a similar voting profile, so they got lumped together.
