It was pretty clear he wasnt going to beat Trump again. His age caught up to him and his debate performance was terrible. His polling was terrible. The right wing propaganda against the Biden crime family was working.  Where Biden failed us the most was not making sure Trump got properly prosecuted in the 4 years he was out of office. A total disgrace that only one indictment made it to trial before election, and couldnt even get to sentencing before it was clear it wouldnt matter against a president-elect.
