I don't think I pointed this out in the Discord server, but one thing that frustrates me most about this map is Cook County being labeled as "Other". What is this mystery denomination of one of the most populous counties in the country?
A subset of historically Black Protestant counted separately?
I thought that too, since Detroit and Cleveland counties are also colored "Other". Blacks make up 25% of Cook. Combine that with the fact that certainly 30 or 40%+ of the county is Catholic, at least, and it seems possible.
