Here’s a precinct map from 2016 that some grad student put together. Feel free to share your partition plan with us.
Notice the part where Alabama has less deep red than the Rustbelt and the Frozen Plains states, or, indeed, rural New England.
Are Alabama and Mississippi still full of stone racists who drop N-Bombs whenever they’re around other white people because they assume all white people are racist like they are? Yeah, sure. Are the blue areas in those states blue largely because of minority voters? Yeah, sure. But that’s not actually all that different from the rest of the lower 48, aside from having fewer social inhibitions about the casual use of a particular racial epithet.
I also note, not without surprise, that Hawaii is, geographically, even redder than Alabama.
