I've lived in rural (and urban-ish) North Louisiana going on 15 years. Mostly deep red, pockets of light blue. I've not seen people organize around any issue like the data centers. They won't beat Amazon's and Meta's money in the short term, but they're ripe for mobilization.
I’ve been screening our documentary with organizing communities in the South. So far, the organizers mention data centers first at every single event. From racial justice orgs to old school activists who don’t usually think about tech policy. This has legs.
