I wish I could say this was a complete surprise. However, the MAGA types are the people I grew up with, in one form or another. Working class, maybe high-school diploma, distrustful of government (of any flavor), the-cops-are-not-your-friends-they-work-for-the-elite, distrust of "outsiders" (aka, anyone not from the region and of their class), universities are dangerous because we don't understand them (except for veterinarian, nursing, and teacher training places). Same with Big Science. They've always been here. Remember the Illinois Nazis and the KKK? They never really went away, just morphed. In Texas they were very fond of unofficial militias... now, THAT was really freaky, when you'd come on platoons of them drilling in full camo & live weapons out in the sticks!
It's the low-income immigrant and borderline (class borders) vote, generically, that surprised me. The people who stand to lose the most have shot themselves in their collective foot. Then again, as much as I like a lot that Biden has done, there are some US foreign policies that leave me absolutely livid. If there had been a viable option to the Dems, and there unfortunately was not, I'd probably have gone down that road.
Welcome to the 1950s, again. Grit teeth, tighten belt, and be ready to do what you can do when you can do it. If you're in a state, or live close to the border with one, unfriendly to women's reproductive rights, you might consider that there will be a need for what might best be called safe-houses. Again. Ditto for Dreamers and other desperate people. [Jeez, it gets older every time it comes 'round.]
