If I was Biden I'd be making it clear that Bernie and Warren will be writing the next bailout bill in the senate, and it will be passed in the first 100 days of my administration if dems win the senate. The covid situation isn't going to be done by November, December, or January. It's unlikely that democrats will get to 60 votes even if they win the senate, but they shouldn't need it to get something substantial done. There will be compromise I'm sure, but the goal should be a bill that gives regular Americans a monthly payment for at least 2-3 months; more small business help; re-funding of the postal service; and an extension of the (generous) unemployment benefits from the previous bill.
You gotta win this out the gate. After that everything (healthcare, college tuition, etc) will be easier.
