Trump's job creation record was the worst of any American president on record, no other modern president
has left the U.S. with a smaller workforce than it had when they took office.

This is where, I think, Democrats miss the point.

Covid happened. Covid negatively affected the economy. DJT is responsible for the existence of Covid, and no set of policy prescriptions that Trump could have implemented (or refrained from implementing) could have prevented Covid from having an enormous negative effect on on things like the workforce. Because Covid had a devastating effect on every economy in the world.

So most voters - correctly - assess Trump's economic record up through the end of 2019 or early 2020 - and don't ding him for the effects of Covid that were outside of his control.

From January 2017 to January 2020, the U.S. economy added 4.7 million jobs - rising from 159.6 million to 164.3 million. It's currently about 168 million.

The economy was doing pretty well under Trump before Covid hit - and Trump's not to blame for the impact of Covid on the economy. There's lots of things that Trump "owns" about the Covid response, but the fact that the labor force declined a lot during that time isn't one of them - because that happened everywhere, and would have happened no matter who was President.
