The COVID crisis obviously has damaged Trump politically, just as it would have damaged any President in office right now. The politicians out there could well seek to leverage that damage by prolonging the pain. I doubt many of "us" would do that, but politicians like POWER. Many are rather unprincipled in my opinion.
Even if you think Trump has handled this badly, he's not unique in that respect if you look at most EU countries. Many are worse off, and their heads of state have suffered as well politically. So, it seems pretty likely that SOME politicians hope to prolong and worsen this for political reasons.
Without it, Trump has a pretty solid campaign item, the economy, that has dissipated, largely. With it, he's obviously vulnerable.
So, at this point, which Democrat in office would want to lessen the impact of the pandemic to the economy? Some probably, not all.
