Voting isn't a particularly social activity, and the incidental contact it involves should be of minimal concern to people who are being careful and not doing something especially stupid.
If the US in general wasn't constantly doing especially stupid shit in relation the covid, there wouldn't be 170 thousand and rising new corpses in this country.
That's simply objectively false. The US has a death rate on par or below that of demographically similar countries, compliance rates for precautions are extremely high (the 'Americans won't wear masks' meme is simply a lie, or at best a failed extrapolation from specific outlier regions), and QALYs lost have been low. There is no statistical basis to think that America has done significantly worse than any other country
relative to its population base, and it's clear that, for example, it is doing much better than the European average. There have been a few mistakes — "stick 'em in the nursing homes" comes to mind for me, a New Yorker — but this is an inevitability in all cases where humans are allowed to make decisions, and there have been mistakes everywhere else too. Nevertheless, to drill down more specifically to whether there should or shouldn't be 170k corpses lying around, all the evidence is that the majority of deaths in America are simply statistically 'carried forward' from the next five to ten years; by any model, normal death rates will be suppressed over the near term due to the slight but significant 'youngening' of the population. From a long-term and especially from an evolutionary perspective, the epidemic has been
good for the population of the country as a whole.
With that said, of course, statistically, we will expect a spike in cases from voting. (Nobody is forced to the polls, though, I must quibble. You can and most people probably should typically just not vote.) Anything which increases contact and therefore risk, however marginally, will cause a detectable spike when the baseline population is so large.
