I have heard my President booed at his rallies twice when bringing up his great work with Operation Warp Speed and the vax, as if it where a great accomplishment.
His hard core fans (like myself) make a great many excuses for a great many things he does that are anti-establishment and we applaud. But if he should survive the primaries the DS will release all the info on the vax being horrific and will make Trump the author of it all.
If Trump plays 5-D chess at all, then he needs to get ahead of it and admit he made a mistake listening to his advisors, like Fauci and the rest.
If he sticks to his guns that he did great things rushing the vaccine and turning Ford into a respiratory manufacturer for useless equipment now going on Ebay for $100 bucks, then he will loose.
We voted for a competent leader because he was not a politician but it seems his brief stay in DC might have turned him into one.
Response to OP's post title:
"why?" That would be a massive miscalculation.
This is playing out exactly as it needs to to show people the lengths the government will go to to preserve itself and its control mechanisms. Blame is rightly being placed on big pharma, Fauci, WHO, CDC, the Chinese, and dumb lefties and sheep everywhere.
I see Covid as a tactical piece, used to leverage influence over several areas of American life simultaneously, including elections, economics, population movement and control, food, and public behavior. There are probably more, too. Seems like it was thrown into the mix to try to get the 16 year plan back on track, and here is where it's running into heavy resistance.
