I don’t think this is an exact proxy for fandom by state, but it is close-ish.
I would expect the Yankees in, I guess, in an “unclaimed” state like Wyoming and even Nebraska, only Omaha of which is tied in anyway to the Royals. And you would expect them in Florida, because Florida.
But how about the Yankees in TN, NC, and SC, states that are contiguous to Georgia, home of the unoffical capital of the region? And I might have thought the New Mexico might have been solidly Diamondbacks, but then, it’s probably one of the lesser baseball states in general. Amd Astros in Alaska? Wouldna thought that.
