Guess you haven’t been looking at Trump’s poll numbers.
And no; people know how deep the swamp is and would not respond to cheap shots like “why didn’t he fire Fauci” or this or that other bureaucrat.
“Why didn’t you fire Fauci?” is hardly a cheap shot. It goes to Trumps inexcusable empowering of that troll , in a way that devastated millions of lives. If Desantis runs ads with banrupted small business owners asking Trump why he stuck by Fauci - and he did- Trump’s primary campaign could be a short one. True believers like you won’t be swayed, but average voters aren’t guided by cult of personality. Trump kept Fauci front and center, and he defended the lockdowns - and even criticized governors who started to open up when Fauci said it was too early. This actually pisses Desantis off, which is a reason that he might surprise people and throw his hat in the ring.
