We've seen this all before and it's become so predictable.
With less confidence, I predict people who get sick, have friends and family get sick, and/or watch their 401k value drop 25% in a month will develop antibodies to certain types of fake news.
With 100% confidence, I predict those people will use all of the things you mention there to further increase the political divide and entrench their already solidified world and political views.
It's practically written in stone at this point.
That's a bit more influential than a liked facebook post with false numbers.
People will just double down. The conspiracy will be that it's just an attempt by the government to get you to vaccinate or something.

I think you undervalue this administration ability to spin. Did you watch President speech yesterday? Everything is wonderful, everything is great and Mike Pence in charge (with at best questionable history of handling crisises in his own state). If you believe we will have real death tolls from Corona and yet Trump will not spin it that into some form of good news (because more haven't died for example?) you haven't paid attention to politics long enough, I'm afraid.
But pretending there wasn't problems with Clinton isn't going to help.
Trump would never have won against Obama for example, but against someone who sh#ts on their core voter base even he had a chance and now Republicans seems to be defending his every move like soccer fans defending their favorite team in spite of all their problems.
(Oh, and the Democrats keep defending Hillary despite all her craziness.)
