has Biden done a good job as president?

which is why i'm asking this question now.. because if you do not know or have some sort of opinion then that in of itself speaks more than anything you can say.

And if that were the case, what exactly would it say?

Trump basically rode on Obama's coattails. One needs a standard of good to determine whether Biden meets it. If Trump is that standard, then absolutely. If other presidents or metrics, then you need to specify them.
