I live in rural Wyoming and it's a huge deal here, if these projects go through many people are affected.
Some of these data centers are multiple orders of magnitude bigger than a blast furnace.
I think people are pissed that they're subsidizing the R+D cost of their own unemployment.
I'm sorry it affects you directly, but the number of people who live in the whole state of Wyoming is around a half-million (even ignoring "rural"). If every single person in the entire state were affected, that would be 1/650th of the population of the United States affected, to say nothing of the world.
There's just no way it's a significant factor in overall sentiment.
