Maybe another perspective on this is that Democrats were preaching to the upper arm of the K-shaped recovery that everything is fine with their bureaucracy in charge (because nobody actually cares about Biden or Kamala personally), and the people on the lower arm voted on "Hell no, it's not!" This was the Springfield, OH thing, where the media tried to laugh it off as a few racists claiming pet-eating, but a small town was truly stretched beyond its limits through illegal immigration.
