I love maps, and I love studying social politics, so I found the image below quite interesting. Having grown up in the deep south, and as the son of a corporate lobbyist, I was steeped in an anti-union tradition even as a small boy. Age has tempered these views somewhat, but I am indeed struck at how light unionization is in my homeland. This is all particularly germane since there is a very important effort on the part of some Amazon warehouse workers to unionize, and the results of that vote, to be learned in the coming days, could have quite an impact.
