I don't know what people are expecting. No candidate can promise to make Trump go away, not with ~half the country in a cult. All you can do is make your best case, whether you're Biden, Harris, or anyone else and hope the voters agree. Anything else is not democracy.
There's lots of room to argue whether Biden is the best messenger, or whether his campaign understands what needs to be said, but of course he's not likely to agree he sucks.
