It seems clear to everyone except Trump himself that he has no path to victory.
He has the opportunity to do one decent thing in his Presidency, and concede gracefully. It's not too late for him to do that. But I doubt he will.
The best thing for America is that he concedes, disappears from then politics completely. And even if state and federal prosecutors have been holding out for him to lose the presidency to prosecute, I think that would just further divide the country. If they have evidence, the best thing for the country would be to strike a quiet deal with him to not prosecute in exchange for him completely removing himself from politics and social media.
