I would not expect a reset either. Frustration/Blame simply seems to be channeled towards those who were already perceived as the antagonist, rather than the actual contributing culprits. That is just my experience.
Even at best, I think blame is inherently directed towards urban mentality and the channels through which the virus originally entered the country, and thus the politicians who they view as supporting urban interests and behavior.
It is complex because areas who went overwhelmingly for Trump don't necessarily hold the same militant attitudes, some might even find behavior like storming the election facilities to be unseemly. Some of it is viewing the world through a political lens ("don't control me"), some from a religion lens ("the other party is immoral in terms of their policies, even if Trump is not a good person"), some of it from pure xenophobia ("Protect us from outsiders"), sometimes a mix. There does tend to be fervent tribalism though -- closing the ranks regardless and defending against outside thoughts.
Despite my home country going overwhelmingly for Trump, looking at the votes, the more urban areas were less Trump (65-70%) and the more rural areas were more Trump (75-80%). My mom lives in a retirement home in the county seat where I was also born (as the main hospital in the area), and it's the "most liberal" in its voting, I see. It's right off the major highway, it's where the courthouse is, etc. Her retirement home has been stringently locked down, access is very much restricted, and activity within the facility is very restricted as well. It seems to have been very successful in avoiding any influx of COVID since March as well. although I know it has been frustrating for them too because it limits direct interactions with even family. those who are trained to be more aware of the realities of COVID (and where impact could be severe) seem to be taking it very seriously in those environments, it's those without awareness or training or need to be so severe that are being more flippant about it.
I am not sure what I'm trying to say, I guess. But I can easily envision even when an individual's behavior in those areas results in them contracting COVID, them blaming an outside influence and basically the "urbanites" for allowing the disease to get out of control and/or delivering it to their area, reinforcing the tendency to isolate and view outsiders with suspicion, rather than viewing their own behavior at fault. But that is not a new thing. AIDS was an 'urban' thing too, to the area I grew up in; and other things they viewed as social ills.
