Perhaps, perhaps not. It seems like a tempting theory but...
Trump's approval has remained pretty dang static throughout his presidency (except for the very first fiew days), in spite of all of the crazy things that have happened over the last 4 years.
In fact, there was a noticeable bump in Trump's approval rating around April 2020, which some attribute to a "rally around the flag" effect whenever a nation is hit with a crisis. However, Trump's bump was pretty small and short-lived compared to the massive and sustained gains that George W. Bush experienced after 9/11 (and didn't fully squander until after the Iraq War drug on for years and years).
Trump issued so many obvious gaffes and missteps on Covid that his numbers fell back to where they had been historically.
Covid-19 was unquestionably the biggest crisis and biggest missed opportunity of his Presidency -- if he'd handled it well and regained the trust of Americans he had lost over the previous years, then it could have been an opportunity for him to win in 2020 despite all the many other reasons to dislike him.
But he simply wasn't up to the task, and that's one big reason I predict he will suffer a crushing defeat next week.
