This exit poll on Coronavirus (nicked from the BBC) is interesting IMO. Given that US policy has been nothing short of disastrous, only 50% of those polled were willing to say it is going badly.
Poll might be a little skewed from being taken on Election Day - more than half the voters went for early voting or mail-in ballots this year, the people who didn't want to go near a potentially crowded polling place on the day probably had more concerns about how the virus was being handled. Although it looks like a lot of them voted for Trump anyway.
