also, fyi without the Senate though, Biden still gets to:
-Undo 90%+ of everything Trump did, since he did 90% of his shit through Executive Orders instead of legislation
-Replace all the corrupt departments like Justice Department, FDA, CDC, EPA, etc...
-Restore foreign relations and trade deals
That will literally takes most of the first 2 years of administration just to do. The two big things they will lose in those years without the senate is any ability to change the supreme court makeup and anything drastically progressive voting rights act/police reform. If they take senate in 2022 (which is an extremely favorable D senate map) they can do all that in the second two year period.
Covid stimulus package would still get through as the R states need it badly.
aka, getting the Senate would be really, really good, but it's still ok if they don't get it.
